After reading the other reviews, I thought I will give it a try and in the end De*nitrate really works, brings down my 60 gal overstocked freshwater tank from 80ppm nitrate to a constant 10ppm, however it takes a lot more effort, brain and money on top of the product itself to create an ideal environment for it. And I think it's worth it. First you need a few things: 1. A media reactor cylindrical and clear 2. Liquid flow meter 3. Flow control valve 4. A pre-filter 5. An after-filter 6. A submersible aquarium pump 7. Shut-off valves 8. Stainless/plastic hose clamps and strong cable ties 9. Clear aquarium vinyl tubing 10. 50 micron filter pads Then you connect the submersible pump to a shut-off valve, through a pre-filter, then through media reactor, out through the liquid flow meter, through the flow control valve, then finally an after-filter which is a 50 micron polishing pad tied to the end of the tube submerged in the aquarium. You want the flow rate to be at around 35gph consistently. To do that, you will have to adjust the flow control valve once in a while as the pre-filter catches more and more debris while it slows down the flow little by little. A few things need to be taken into consideration: 1. You need a pump that has a flow rate of at least three times of 35gph just to handle the media reactor and pre-filter, then add roughly additional 100gph for 50 micron polishing pad because it slows down the flow significantly. Finally another 50gph as the flow rate gets slowed down little by little in the long run while it catches more and more debris. 2. You need to use your liquid flow meter to read your current flow rate easily and adjust accordingly. 3. Do not cheap out on a pre-filter, make it big, in diameter, not in length. The bigger diameter it has, the longer it takes to slow down the flow significantly hence the longer time periods it provides until maintenance. 4. Put a 50 micron filtering pad inside your pre-filter. This will provide longer working time for your media reactor before it gets clogged up by debris which then it would require a complete rinsing of the media itself. 5. It can be pain in the ass when it comes to the tubing size. The best case scenario would be one size fits all when your pump, your pre-filter, your media reactor, your flow meter all require the same tube size, if not, then you would need multi-hose adapter which adds to the work and cost. 6. Always use clamps in every joint to prevent potential leak. Use plastic cable ties or hose clamps instead of metal clamps for underwater applications. 7. Add shut-off valve at the ins and outs of your pre-filter and media reactor for easy maintenance. 8. After every time you rinse your media, add tiny bit of sugar at the bottom and middle of your reactor as the anaerobic bacteria need a carbon source to thrive. 9. Last but not least, your will need an alkaline buffer and aquarium minerals because once water change becomes less and less often, maintaining a healthy PH and vital minerals level becomes more and more important.
Hey, I recently purchased a Korallin S-1502 sulfur reactor for my reef tank from Marine Depot and I have a few questions about tuning nitrates. I installed my unit with 50% of the Sulfur media & 100% of the calcium media (wasn’t much) in my 15 gallon refugium for my 60 gallon reef tank (~75 gallons total). Here’s the events of what happened so far: -Nitrates in the tank and reactor started at 40ppm -I let the reactor run at 1 drop/second every day & tested nitrates every day -After 8 days nitrates dropped to 2ppm out of the reactor, the tank was still at 40ppm -I let the reactor run for 3 more days at this rate and watched nitrates reduce from 40ppm to 20ppm to 5ppm in the tank, reactor still outputs 2ppm -I increased to 2 drops/second and ran it for one week, nitrates in the tank reduced to match the sulfur reactor, both are now 2ppm. I stopped doing daily nitrate tests as the instructions said I could stop here -Another week went by and the reactor outputs 2ppm, but the tank rose to about 12ppm -I increased the reactor to 4 drops/second -Within one hour my tank was cloudy (I think it’s the bacteria coming out of the reactor) but I left the reactor run anyways for 3 more days without testing -After that I tested nitrates and saw 20ppm coming out of the reactor and the same for the tank -Using the Korallin instructions I backed down to 2 drops/second and tested everyday -After 2 days the reactor output was back down to 2ppm, and the tank back to 5ppm and let it run another week -Now on the 3rd week of install I am facing the same issue, nitrates in the tank rose to 15ppm and I tried increased the flow to 4 drops/second on the reactor - but the exact same thing happened again and the tank got cloudy - I backed down again to 2 drops/second and the tank nitrates are now sitting around 10ppm *I am asking for advice on the best way to proceed so I do not have to “chase” these nitrates when I see nitrates rise Other users mention they increase the drip rate everytime they hit 0ppm on the reactor’s output until they get to a full stream. I only made it to 2 drops/second which seems very low in comparison to others. On the other hand the Korallin instructions (as bad as they are) read as though you will find a “goldie locks” zone where you stop increasing the output once the tank hits a desired level, in my case this was 2 drops/second. Has anyone seen a tank get cloudy while using a sulfur reactor? Should I move the input/output of the reactor directly into the tank instead of the refugium? Moving forward I am considering the following, and appreciate any input -Let the reactor run at 4 drops/second for another ~8 days to see if it bottoms out again. Maybe I didn’t wait long enough? -Add more sulfur to the reactor, it is rated for 150 gallons so cutting the media in half seemed like a good starting point, however this may not work because I don’t have my reactor output fully open. I would imagine one would add more media when the system is running at full throttle and the nitrates still aren’t low enough.
Adjusting the flow rate in the reactor sounds like it may be the best option but, we recommend reaching out to our support team at customercare@marinedepot.com and they should be able to troubleshoot the unit with you.
I know you folks focus on saltwater but can this method also be used for freshwater? I've been controlling nitrates through water changes but would like to move to something like this. I'm just not sure if the water coming out through the sulphur might be fine for a saltwater environment but is not OK for freshwater. Thanks for this video!
I have the Aquamaxx reactor but do not feel like it's doing anything. Do you have to use a starter culture in it to establish the bacteria? I have water passing through it and its slowly dripping into the sump but still have high nitrates.
+Jung Houn Sim I am interested as well. from what i gather water re-circulation is a key to these reactor's efficiency. I have read you could use basically any reactor is the flow is kept very slow, but would not be as efficient as one that has a pump recirculating.
Yes, but the effectiveness is all about the media you decide to place inside the reactor. Biopellets will need a sufficient method to export biofilm (protein skimmer) which is not used in freshwater aquaria. You might consider an algae turf scrubber instead or increase water change frequency for the most effective remedy. If your tank is overstocked or full of larger fish, look into an auto water exchange system.
do you need to change the denitrate??? I have had it in my tank for almost 1 yr and my nitrates are at 2 ppm or less... which I'm not complaining... but wonder if it needs to be changes at some point???
I am putting together a new 36 gallon and its up and cycled with 3 fish. I have a skimmer to hook up and a media reactor and was going to buy somemore stuff when I order the lights but not sure which way to go being I am a newbie and just have a 10 gallon hob before. So far I have about 30 marine pure bioballs in my sump and were bought live in a bucket with live rock. My nitrates have fallen to looks like zero on an api test kit but next color is 5 which is quite a jump isnt it? Should a person stay around 0.03 or something? I dont have any corals yet and I get up leftover food and change filter socks every 3 days and since skimmer isnt hooked I am changing 15 percent water about evry 8 to 10 days. Is it possible that bioballs work so well I dont need anything alse at least now being I have no corals? Probably best to do a wait and see approach and I do have no pox on hand, a brand new bottle that came with the used tank.. I dont need to dose so I guess all I need for now is lights! I have a new paypal zero interest and the more I spend the longer I get to pay it off with zero interest@ haha I just realized that I am also using microbe lift special care. It is sulpur base and nitrate bacteria. I picked it up to go with their other bactria to use after big water changes. Both were on sale for 5 bucks a bottle at petco and and special care is added once a week for a few months then I think once a month so maybe this stuff or the combo is working just fine and very cheap! Stinks to high heaven! haha
Phytoplankton would really have to be cultivated and removed from the system at a high rate in order to have any effect. Since you cannot exactly isolate the phytoplankton or filter it out of your tank water efficiently; you would not be able to "export" the nutrients it consumes and therefore it would stay inside your tank.
The nutrients would still never be "exported" from your system in this case. Only transferred from the clams to the fish. I have no experience with this sort of approach but I imagine it would take a big population of clams to consume a noticeable amount of nutrients.
i have a 55 gallon fresh water tank, and looking to upgrade later. my water source has high nitrate level so doesn't matter how many time i do wc, nitrae still high above 40ppm. will this help lower my nitrate problem? what kind of pump will be suited for this denitrator? will it loud?
I would recommend getting an RO/DI system to filter the tap water that goes into your aquarium. For freshwater tanks, you can utilize the RO water and when you switch over to saltwater, the RO/DI water will be perfect. I provided a link to shop RO/DI systems on our website below along with a couple of videos all about RO/DI systems. mdshop.us/29DuwZB mdshop.us/29Opddk

For a 14 gallon saltwater would throwing a small bag of this stuff somewhere in the filter area be worthwhile in helping to keep such a small tank more stable or is there something else that would be better? Not looking to hang some huge extra equipment on the side.
I have question regarding seachem denitrate, I have lots that's bean in storage and developed algae over the course of the year. Can I clean the stones by soaking in thin bleach and ro then soaking them in ro and prime? Like purigen? Or is this totally crazy? Thanks
Just to be safe, I would stay away from bleach because the media is so porous. You can probably clean the rocks by letting them dry first, then soak and rinse thoroughly in clean RO water. -Robert @ MD
I'm a little confused. If sulfur is added as a carbon source for the anaerobic bacteria to denitrify the water then what is providing the carbon source in something like seachem de*nitrate?
hi, currently my nitrate is 200 plus and now im using DVH Biopellets with reactor for 3 weeks but ritrate still around 200. Can i use DVH biopellets reactor and de nitrate reactor run together ? does it help ?
I'm having major nitrate problems. 160+ using api test kit. I don't have room for a protein skimmer. I did a water change last night and this afternoon went home to test my water and Nitrites are up to 5+ ppm and nitrates 160+ still. the nitrate test results look as red as blood. and nitrites test results are pure purple. When I did the WC last night I tested all the water before putting it in the tank. I did a 80% water change and did not feed with ammonia or anything else. which i'm trying to avoid cause surely there is something in my tank causing the high nitrites and nitrates. I have about 20 lbs of live rock and 40 lbs of dry rock. hob filter. 60 g. tank, two heaters, two air pumps and a wave maker and live sand.. now at lunch I did readjust the wave maker to blow in the direction of the rock in case there isn't good flow. I'm hoping this will resolve it a little bit by the time I get home. I really don't want to do another major water change. but if I have to. I'll do a 100% WC. Plus this is a brand new aquarium. so i think i'm 30 days in the cycling.
A new aquarium takes time to establish and elevated ammonia, nitrite and then nitrates are typical. You have a source of waste somewhere, whether you added fish too soon or just a lot of die off from the live rock causing elevated waste. So long as you do not have fish in the tank, it is best to let the tank run through the cycle process completely before performing any more water changes. After 4-6 weeks, you should see a high nitrate level with zero ammonia and nitrites. This is the time to do a large water change and slowly introduce animals. If the nitrites and ammonia are persistent, you want to look at your biological filtration and maybe consider adding some additional mechanical and chemical filtration on the aquarium to help control waste levels. When ammonia and nitrites are present, this means the biological foundation in the tank is not sufficient enough to handle the waste that is going into the aquarium. I hope this helps and feel free to give us a call or shoot us an email anytime for further support. 1-800-566-3474 customercare@marinedepot.com
Hi I watch the video and I'm going to buy some of the products to help lower my nitrates. I have two filters on my tank. I'm doing water changes once a week. And I feed my fish every other day I still having problems with high nitrates. I was wondering if you can help does a UV sterilizer help lower nitrates??
No, a UV sterilizer will have no significant effect on nitrates in the aquarium water. Small frequent water changes on a weekly basis is the best method to keep it under control. You also may want to check your mechanical or biological filtration on the tank that could be trapping debris. Rinsing and keeping this type of filter media free of debris is important when trying to avoid high nitrate levels.
What can you do to control the sulfur smell coming out of the denitrator? I'm starting to smell it in my house. My denitrator has been running for about 2 months now.
This is pretty typical with these reactors and a small bag of carbon should help to get rid of the smell or at least reduce it. If the smell seems to be getting worse or is strong, it could be that you are running too slow through the reactor which can lead to the production of Hydrogen Sulfide gas which is most likely what you are smelling. Try increasing the flow rate a bit and see if that helps. -Robert @ MD
+JoeKoors If you want to lower nitrates, the Kent Marine and Seachem are both an excellent choice and work great. Just be sure to keep the flow rate very slow. mdshop.us/1NiBp5z
Yes, I would like to see how stable the TS-1 is in simple terms of standing upright. It looks as if the pump off to the side might cause it to tip easily. I had a Reef Octopus 110INT skimmer that was so poorly designed it was incapable of simply standing upright, and had to be secured. (Actually it was awful on MANY levels and I had to get rid of it!)
Hello, I've recently installed a sulfur dinitrator. Inside the unit I have zero nitrates and 20 in my tank. From 45. So it's working great but heres my issue. The unit is very cloudy and every drip is cloudy witch is causing the tank to go cloudy. What could be causing this? Tank size 150true gallons but unit is 8"diameter by 18" tall. 2/3 is sulfur and 1/3 crushed coral and dinitrate rocks. Same as video. Please help
The reason for the slow flow rate is that you want the anaerobic bacteria to have enough contact with the nitrate to extract the oxygen and break it down.
Sorry to be so offtopic but does anybody know a trick to get back into an instagram account?? I was stupid forgot the login password. I appreciate any tips you can give me!
@Jedidiah Cyrus Thanks for your reply. I got to the site thru google and im trying it out now. I see it takes quite some time so I will reply here later with my results.
Hoping you are still answering questions on this old video. I’m looking at adding a biopellet reactor to my freshwater tank to help with a heavy overstock/nitrate problem. I’m not overly dangerous levels but no matter how many water changes, filter cleans and gravel vacs I can not get my main tank under 50-60. Not unheard of for a cichlid tank and kids the norm really. But would love to use a reactor to balance out to 20-40ppm and reduce water changes. I’ve done tons of research and can not find the proper answer to this.. when running a reactor on a freshwater aquarium do you need a protein skimmer? In the world of freshwater, protein skimming is a DO NOT do and if done a waste of time. As our bacteria work the same but are different species most protein surface film is simply removed with surface agitation and good filtering. I’ve found a couple short non informative comments on people simply running UV filters which I already have and never having any sort of surface buildup. My fear is I know the carbon based media adds tons of waste through its own breakdown and last thing I want to do is have a redox issue cause of a biofilm. I run two canisters with outlets at or above water surface (depends on current state of evap) plus several air stones so I have tons of water turnover around 13x an hour between power-heads and filters and filtering turnover of around 6-7x and hour w/ media. fine filtration like poly and chemipure along with tons of surface agitation. My gut and experience says I simply need a reactor an no skimmer.
In order for bio-pellets to be effective you must remove the "bio-film" which is how the nitrate is exported from your system. In a saltwater aquarium this is done with a protein skimmer. In a freshwater system, this will be difficult to accomplish and I would not recommend it. Consider an algae scrubber or look at one of the new nitrate resin medias.

JBL do a pillow called nitraEX, my tap water is 40ppm so warter changes didnt do a damn thing....found jbl nitatex and used it in a small internal filter inside a big water tub i used for water changes. b4 a water change id run the filter in the tubs tap water and it would bring down my nitates from 40ppm to 5ppm, also added a pillow to my tank and it works 100%. after a while u need to recharge the nitatex pillow with a salt solution and its good to go again. have u tested your tap water for nitrates? my fish shop said that the legal limit is 40ppm so im unlucky where i live.
Great info. What about vodka dosing (Aquaripure)? I have been using the Aquripure for a couple of years now. the sulfur looks very interesting. Thanks for your videos.
+Steven Klink I am doing sugar-dosing with excellent results. Very fast algae blooms (within 1 day) and then everything is skimmed out quickly. You must have a good skimmer but same concept. Although this also takes nutrients from the water. I do not do this daily like some. I do it maybe monthly if that. My 220 is not heavily stocked. Mostly corals.
I've had my Koralin denitrator for about 3 months now, and my nitrates are still at 100 ppm coming out of the reactor. At this point I would say don't waste your money, despite the good reviews on the MD website. I posted a fair review, and it didn't seem to make the page, and when I try to update it, it just tells me I've already reviewed this product. I've been buying products from them for over 10 years, but this makes me go hmmmm.

Thanks again and happy reefkeeping! -Robert @ MD
i know that it can take up to 7 or 8 months before there is enought bacteria to low your nitrate. sometime the ratio isnt good and it take more time.. 1/2 of the total size of your reactor must be sulfur, and in the remaining space,1/3 or 1/4 of aragonite of the remaining space between sulfur and the top of the reactor.. i hope youll fix your probleme cause this method is definitivly the best in term of big drop of nitrate.. better than nopox(cause nopox use nitrate AND phosphat) so, if you'r low phosphat like me, it didnt work at all..but sulfur reactor creates bacteria that eat sulfur AND air, in your reactor you should not have any air,(except nitrates)and there is where the magic start.. so be sure you dont have any air leak,be sur your reactor is (1 drop per seconde the first months, until your between 0 and 2 nitrate and 0 nitrite(in the exit of the reactor of corse,and not in the aquarium),then you can put it 2 or 3 drop/sec etc..until you reach 2 or 5 nitrate in your tank) and with the good ratio !! hope it will help you like it helped me !(pardon my english)
Yes, when operating correctly you can see the nitrates drop via a water test. Simply test your tank water first then compare to a water test of the water that is existing the reactor. You will see a substantial drop in Nitrate and is one of the steps you will need to take when dialing the reactor in.
After reading the other reviews, I thought I will give it a try and in the end De*nitrate really works, brings down my 60 gal overstocked freshwater tank from 80ppm nitrate to a constant 10ppm, however it takes a lot more effort, brain and money on top of the product itself to create an ideal environment for it.

-I increased to 2 drops/second and ran it for one week, nitrates in the tank reduced to match the sulfur reactor, both are now 2ppm. I stopped doing daily nitrate tests as the instructions said I could stop here
-Another week went by and the reactor outputs 2ppm, but the tank rose to about 12ppm
-I increased the reactor to 4 drops/second
-Within one hour my tank was cloudy (I think it’s the bacteria coming out of the reactor) but I left the reactor run anyways for 3 more days without testing
-After that I tested nitrates and saw 20ppm coming out of the reactor and the same for the tank
-Using the Korallin instructions I backed down to 2 drops/second and tested everyday
-After 2 days the reactor output was back down to 2ppm, and the tank back to 5ppm and let it run another week
-Now on the 3rd week of install I am facing the same issue, nitrates in the tank rose to 15ppm and I tried increased the flow to 4 drops/second on the reactor - but the exact same thing happened again and the tank got cloudy
- I backed down again to 2 drops/second and the tank nitrates are now sitting around 10ppm
*I am asking for advice on the best way to proceed so I do not have to “chase” these nitrates when I see nitrates rise
Other users mention they increase the drip rate everytime they hit 0ppm on the reactor’s output until they get to a full stream. I only made it to 2 drops/second which seems very low in comparison to others.
On the other hand the Korallin instructions (as bad as they are) read as though you will find a “goldie locks” zone where you stop increasing the output once the tank hits a desired level, in my case this was 2 drops/second.
Has anyone seen a tank get cloudy while using a sulfur reactor?

I used this method for 4 aquariums now. Works great.
I have a question i been using it for 5 months and my water inside the reactor it smells like rotten water is that normal?
How efficient is this? Can you guys do an upgraded video on the denitrator media only?
I know you folks focus on saltwater but can this method also be used for freshwater? I've been controlling nitrates through water changes but would like to move to something like this. I'm just not sure if the water coming out through the sulphur might be fine for a saltwater environment but is not OK for freshwater. Thanks for this video!
Why is the CaribSea LSM no longer available to purchase?
Unfortunately, it has been very hard to source the media for the reactor.
I have the Aquamaxx reactor but do not feel like it's doing anything. Do you have to use a starter culture in it to establish the bacteria? I have water passing through it and its slowly dripping into the sump but still have high nitrates.
Any difference between the korallin and aquamaxx denitrators that would make you recommend one over the other?
Both are great options! We have the most expansive knowledge on and handle all support for the AquaMaxx system.
Would one of these nitrate reactors work ina cold water fancy goldfish aquarium?
Would love to see a video on the setup and operation of the AquaMaxx TS-1 or 2 Sulfur Denitrators
+fudsey We will keep this in mind for a future video. Thanks for watching!
Right, I spent $350 and the instructions are TRASH.
@@tblev6885 Seconded. The quotes on the side of an empty packet of Taco Bell hot sauce are more helpful than the instructions in the box.
where can you buy that from??
We are working on getting our biological denitrators back in stock and we should have them available on our website soon.
I can use any media reactor for this correct? If not what is the design difference on these compared to let's say a phosban 150. thanks!
+Jung Houn Sim I am interested as well. from what i gather water re-circulation is a key to these reactor's efficiency. I have read you could use basically any reactor is the flow is kept very slow, but would not be as efficient as one that has a pump recirculating.
Hello, I have a question sir. If you are using a sulphur reactor, do you still need to dose carbon?
Can you use a media reactor to lower nitrates in fresh water tank and use as a hangover the side style?
Yes, but the effectiveness is all about the media you decide to place inside the reactor. Biopellets will need a sufficient method to export biofilm (protein skimmer) which is not used in freshwater aquaria. You might consider an algae turf scrubber instead or increase water change frequency for the most effective remedy. If your tank is overstocked or full of larger fish, look into an auto water exchange system.
biopellets, refugium, 20% wc by weekly haa worked for me but id be willing to try some of these new things.
do you need to change the denitrate??? I have had it in my tank for almost 1 yr and my nitrates are at 2 ppm or less... which I'm not complaining... but wonder if it needs to be changes at some point???
+Alberto Amigon No, the media does not need to be changed out since it is only acting as a home for the bacteria which is doing all the work.
Will these type of denitrators work in a cold water fancy goldfish aquarium?
I am putting together a new 36 gallon and its up and cycled with 3 fish. I have a skimmer to hook up and a media reactor and was going to buy somemore stuff when I order the lights but not sure which way to go being I am a newbie and just have a 10 gallon hob before.

Probably best to do a wait and see approach and I do have no pox on hand, a brand new bottle that came with the used tank.. I dont need to dose so I guess all I need for now is lights! I have a new paypal zero interest and the more I spend the longer I get to pay it off with zero interest@ haha I just realized that I am also using microbe lift special care. It is sulpur base and nitrate bacteria. I picked it up to go with their other bactria to use after big water changes. Both were on sale for 5 bucks a bottle at petco and and special care is added once a week for a few months then I think once a month so maybe this stuff or the combo is working just fine and very cheap! Stinks to high heaven! haha
0:47 It says macroalgae but would phytoplankton do the same if you had a lot of it?
I am not exactly sure of your question but we want to help. Feel free to email or call us directly.

What I mean is, in minute 0.47 is says macroalgae will consume nitrates, would phytoplankton do so too?
Phytoplankton would really have to be cultivated and removed from the system at a high rate in order to have any effect. Since you cannot exactly isolate the phytoplankton or filter it out of your tank water efficiently; you would not be able to "export" the nutrients it consumes and therefore it would stay inside your tank.
Could I use clams to consume it in their tissue and then use them as a food source for my fish?
The nutrients would still never be "exported" from your system in this case. Only transferred from the clams to the fish. I have no experience with this sort of approach but I imagine it would take a big population of clams to consume a noticeable amount of nutrients.
i have a 55 gallon fresh water tank, and looking to upgrade later. my water source has high nitrate level so doesn't matter how many time i do wc, nitrae still high above 40ppm. will this help lower my nitrate problem? what kind of pump will be suited for this denitrator? will it loud?
I would recommend getting an RO/DI system to filter the tap water that goes into your aquarium. For freshwater tanks, you can utilize the RO water and when you switch over to saltwater, the RO/DI water will be perfect. I provided a link to shop RO/DI systems on our website below along with a couple of videos all about RO/DI systems.

What size would I need for a African cichlid 180? Size or model
How long you need to replace Sulphur? Or is it need refilling?
Does reacted need to be clean?
Also do I need to continue carbon dosing with no pox if I'm using this method?
Do u have to change out the lms media out
Yes, but it only needs changing out every couple of years.
For a 14 gallon saltwater would throwing a small bag of this stuff somewhere in the filter area be worthwhile in helping to keep such a small tank more stable or is there something else that would be better? Not looking to hang some huge extra equipment on the side.
I have question regarding seachem denitrate, I have lots that's bean in storage and developed algae over the course of the year.
Can I clean the stones by soaking in thin bleach and ro then soaking them in ro and prime?
Like purigen?
Or is this totally crazy?
Thanks
Just to be safe, I would stay away from bleach because the media is so porous. You can probably clean the rocks by letting them dry first, then soak and rinse thoroughly in clean RO water.
-Robert @ MD
Thanks for your advice ;)
Will these only work with saltwater tanks, or do these work with freshwater tanks also?
Yes, the methods discussed in this video are suitable for freshwater aquariums as well.
-Robert @ MD
I'm a little confused. If sulfur is added as a carbon source for the anaerobic bacteria to denitrify the water then what is providing the carbon source in something like seachem de*nitrate?
What are your thought on using seachem hypersorb and or purigen in a reactor in stead of the biopellet, etc...
In a denitrator?
Marine Depot Aquarium Supplies in a reactor, like biopellet.
hi, currently my nitrate is 200 plus and now im using DVH Biopellets with reactor for 3 weeks but ritrate still around 200. Can i use DVH biopellets reactor and de nitrate reactor run together ? does it help ?
I'm having major nitrate problems. 160+ using api test kit. I don't have room for a protein skimmer. I did a water change last night and this afternoon went home to test my water and Nitrites are up to 5+ ppm and nitrates 160+ still. the nitrate test results look as red as blood. and nitrites test results are pure purple. When I did the WC last night I tested all the water before putting it in the tank. I did a 80% water change and did not feed with ammonia or anything else. which i'm trying to avoid cause surely there is something in my tank causing the high nitrites and nitrates. I have about 20 lbs of live rock and 40 lbs of dry rock. hob filter. 60 g. tank, two heaters, two air pumps and a wave maker and live sand.. now at lunch I did readjust the wave maker to blow in the direction of the rock in case there isn't good flow. I'm hoping this will resolve it a little bit by the time I get home. I really don't want to do another major water change. but if I have to. I'll do a 100% WC. Plus this is a brand new aquarium. so i think i'm 30 days in the cycling.
A new aquarium takes time to establish and elevated ammonia, nitrite and then nitrates are typical. You have a source of waste somewhere, whether you added fish too soon or just a lot of die off from the live rock causing elevated waste.
So long as you do not have fish in the tank, it is best to let the tank run through the cycle process completely before performing any more water changes. After 4-6 weeks, you should see a high nitrate level with zero ammonia and nitrites. This is the time to do a large water change and slowly introduce animals. If the nitrites and ammonia are persistent, you want to look at your biological filtration and maybe consider adding some additional mechanical and chemical filtration on the aquarium to help control waste levels. When ammonia and nitrites are present, this means the biological foundation in the tank is not sufficient enough to handle the waste that is going into the aquarium.
I hope this helps and feel free to give us a call or shoot us an email anytime for further support.

I would gravel vac the sand every time you change water. From my experience working with people they do not do it.
Hi
I watch the video and I'm going to buy some of the products to help lower my nitrates. I have two filters on my tank. I'm doing water changes once a week. And I feed my fish every other day I still having problems with high nitrates. I was wondering if you can help does a UV sterilizer help lower nitrates??
No, a UV sterilizer will have no significant effect on nitrates in the aquarium water. Small frequent water changes on a weekly basis is the best method to keep it under control. You also may want to check your mechanical or biological filtration on the tank that could be trapping debris. Rinsing and keeping this type of filter media free of debris is important when trying to avoid high nitrate levels.
Great video
+Edward Thayer Thanks for watching!
What can you do to control the sulfur smell coming out of the denitrator? I'm starting to smell it in my house. My denitrator has been running for about 2 months now.
This is pretty typical with these reactors and a small bag of carbon should help to get rid of the smell or at least reduce it. If the smell seems to be getting worse or is strong, it could be that you are running too slow through the reactor which can lead to the production of Hydrogen Sulfide gas which is most likely what you are smelling. Try increasing the flow rate a bit and see if that helps.
-Robert @ MD
We will convert NO3 to SO4 and then we need to treat possible H2S gas. Only if Ca carbonate was used not for this purpose to convert SO4 to CaSO4
what product would you recommend for a two little fishes 150? the kent marine? i can give extremely low flow off my manifold.
+JoeKoors If you want to lower nitrates, the Kent Marine and Seachem are both an excellent choice and work great. Just be sure to keep the flow rate very slow.

There should be a video of it in use on a tank update how it works
Great idea! In this case we covered a couple of different methods but I will keep this on my list for a future video.
Yes, I would like to see how stable the TS-1 is in simple terms of standing upright. It looks as if the pump off to the side might cause it to tip easily. I had a Reef Octopus 110INT skimmer that was so poorly designed it was incapable of simply standing upright, and had to be secured. (Actually it was awful on MANY levels and I had to get rid of it!)
Do u have to add veovit to the system
+Jordan Williamson When using a Biological denitrator it is not necessary to utilize ZeoVit media or additives.
what is your opinion for biohome ultimate? can anyone achieve nitrates reduction ?
Do these methods work in freshwater aquariums?
Hey makeba video how set up the biodenitrator pliz pliz im beggin you
Thanks a lot 😊😊
+Jordan Williamson Thanks for watching!
-Robert @ MD
can this be used in freshwater tanks?
I click the link to buy the product and it says me to some bogus website?
Hello, I've recently installed a sulfur dinitrator. Inside the unit I have zero nitrates and 20 in my tank. From 45. So it's working great but heres my issue. The unit is very cloudy and every drip is cloudy witch is causing the tank to go cloudy. What could be causing this?
Tank size 150true gallons but unit is 8"diameter by 18" tall. 2/3 is sulfur and 1/3 crushed coral and dinitrate rocks. Same as video. Please help
too much flow would be my guess
does this work for freshwater aquariums
So I know you have to keep the flow rate low when using a de-nitrification reactor. But I don’t know why?
The reason for the slow flow rate is that you want the anaerobic bacteria to have enough contact with the nitrate to extract the oxygen and break it down.
Sorry to be so offtopic but does anybody know a trick to get back into an instagram account??
I was stupid forgot the login password. I appreciate any tips you can give me!
@Atlas Sutton instablaster :)
@Jedidiah Cyrus Thanks for your reply. I got to the site thru google and im trying it out now.
I see it takes quite some time so I will reply here later with my results.
@Jedidiah Cyrus It worked and I actually got access to my account again. I'm so happy!
Thank you so much, you saved my ass !
Hoping you are still answering questions on this old video. I’m looking at adding a biopellet reactor to my freshwater tank to help with a heavy overstock/nitrate problem. I’m not overly dangerous levels but no matter how many water changes, filter cleans and gravel vacs I can not get my main tank under 50-60. Not unheard of for a cichlid tank and kids the norm really. But would love to use a reactor to balance out to 20-40ppm and reduce water changes.
I’ve done tons of research and can not find the proper answer to this.. when running a reactor on a freshwater aquarium do you need a protein skimmer?
In the world of freshwater, protein skimming is a DO NOT do and if done a waste of time. As our bacteria work the same but are different species most protein surface film is simply removed with surface agitation and good filtering. I’ve found a couple short non informative comments on people simply running UV filters which I already have and never having any sort of surface buildup. My fear is I know the carbon based media adds tons of waste through its own breakdown and last thing I want to do is have a redox issue cause of a biofilm. I run two canisters with outlets at or above water surface (depends on current state of evap) plus several air stones so I have tons of water turnover around 13x an hour between power-heads and filters and filtering turnover of around 6-7x and hour w/ media. fine filtration like poly and chemipure along with tons of surface agitation. My gut and experience says I simply need a reactor an no skimmer.
In order for bio-pellets to be effective you must remove the "bio-film" which is how the nitrate is exported from your system. In a saltwater aquarium this is done with a protein skimmer. In a freshwater system, this will be difficult to accomplish and I would not recommend it.
Consider an algae scrubber or look at one of the new nitrate resin medias. Here is a couple of links for you to check out.

JBL do a pillow called nitraEX, my tap water is 40ppm so warter changes didnt do a damn thing....found jbl nitatex and used it in a small internal filter inside a big water tub i used for water changes. b4 a water change id run the filter in the tubs tap water and it would bring down my nitates from 40ppm to 5ppm, also added a pillow to my tank and it works 100%. after a while u need to recharge the nitatex pillow with a salt solution and its good to go again. have u tested your tap water for nitrates? my fish shop said that the legal limit is 40ppm so im unlucky where i live.
Great info. What about vodka dosing (Aquaripure)? I have been using the Aquripure for a couple of years now. the sulfur looks very interesting. Thanks for your videos.
+Steven Klink I am doing sugar-dosing with excellent results. Very fast algae blooms (within 1 day) and then everything is skimmed out quickly. You must have a good skimmer but same concept. Although this also takes nutrients from the water. I do not do this daily like some. I do it maybe monthly if that. My 220 is not heavily stocked. Mostly corals.
Does your AquaPure work to your satisfaction? I am looking at this too.
I’m anxiously wanting to be successful and maintain a healthy system, how do I increase my bioload?
I've had my Koralin denitrator for about 3 months now, and my nitrates are still at 100 ppm coming out of the reactor. At this point I would say don't waste your money, despite the good reviews on the MD website. I posted a fair review, and it didn't seem to make the page, and when I try to update it, it just tells me I've already reviewed this product. I've been buying products from them for over 10 years, but this makes me go hmmmm.

Bill Schroeder
i know that it can take up to 7 or 8 months before there is enought bacteria to low your nitrate. sometime the ratio isnt good and it take more time.. 1/2 of the total size of your reactor must be sulfur, and in the remaining space,1/3 or 1/4 of aragonite of the remaining space between sulfur and the top of the reactor.. i hope youll fix your probleme cause this method is definitivly the best in term of big drop of nitrate.. better than nopox(cause nopox use nitrate AND phosphat) so, if you'r low phosphat like me, it didnt work at all..but sulfur reactor creates bacteria that eat sulfur AND air, in your reactor you should not have any air,(except nitrates)and there is where the magic start.. so be sure you dont have any air leak,be sur your reactor is (1 drop per seconde the first months, until your between 0 and 2 nitrate and 0 nitrite(in the exit of the reactor of corse,and not in the aquarium),then you can put it 2 or 3 drop/sec etc..until you reach 2 or 5 nitrate in your tank) and with the good ratio !! hope it will help you like it helped me !(pardon my english)
Bill Schroeder i takes 6 plus months to develop anorobic bacteria..
How do I use a biodenitrator with out skimmer? I have know way to oxygenate my livestock.
I have a question i been using it for 5 months and the water inside the reactor smells like rotten water is that normal?
You have too much sulfur media I believe, take a cup out and keep running it
my experience has been it takes way longer than 3 or 4 weeks to start working more like 6 months to a year
Ok thanks a lot
I’m curious to know if this is a proven method?
Yes, when operating correctly you can see the nitrates drop via a water test. Simply test your tank water first then compare to a water test of the water that is existing the reactor. You will see a substantial drop in Nitrate and is one of the steps you will need to take when dialing the reactor in.
Should I run bio pellets while cycling my tank
👍👍👍
Should we change this biological media sometimes or never?
The crushed coral can simply be rinsed and reused periodically. The sulfur media will get consumed and eventually need replacement.
I mean lms
I don't even have a fish how did i get here
media looks so much like cheap pumice.
