Looking forward to seeing the motor operated ball valve! Exactly what I plan to do on my 500g!
Right on! I just have to get my thumb out of my…
This is a beautiful idea
I've gone through the co2 scrubber installation without much help and the media expiring quickly, but this is brilliant. Just ordered some soda lime to try it with some extra parts I have laying around
Glad it was helpful! Should see some great results :)
@@viking_reefing Just set one up today using a BRS dual reactor I wasn't using. Got some soda lime online for the chambers - will update with results!
@@JamesdeGrood looking forward to it!
Thanks for the videos brother🤙🏻
My pleasure!! 😀
Great informative video 👏🏻
Glad it was helpful!
Great video!👍🏾
Glad you liked it!
The easiest way for me to think about pH and ORP is pH=-log[H+] where H+ is looking for an electron, thus is an O in ORP. Increasing the pH lowers the H+ and increases the [OH-], thus less O and more R. This is a drastic over simplification and should only be consumed with beer.
Haha, I believe I follow your logic but might as well crack open a beer to be safe 😂
Great video indeed 😁. I love your torches, how do you keep them so happy?
Thanks! Honestly…not a lot. I basically just run a sps tank and they just happen to be in there
I started experimenting with Kalkwasser last December, initially with a vat of RO/Kalk mixed water added overnight. Then I bit the bullet and purchased a Kalkstirrer and a continous duty dosing pump. I know approximately what my evapouration rate is, however my Kalk dosing is controlled by my pH probe anything under 8.2 and the dosing pump turns on, which is overnight. My pH range is between 8.18 to 8.38. I would like to flatten that curve a little bit more but I have to consider the amount of RO water I am adding. During the day I add All for Reef to take care of the Trace elements and the Mg.
Kalk works great. What I did is that I figured out what my daily evaporation was and made up for about 90% of that during the night. However, I must say that I’m liking the co2 scrubber a lot more as there’s basically nothing to clean or refill.
What I found to be a headache is that your evaporation really changes throughout the year based on ambient humidity.
Great tank! Why not one larger media container instead of the two? What search term should I use for finding a source for the media in the USA? Or do you have a suggestion?
My thinking is that all the media in camber 2 won’t be spent ones the oh starts to dip. That way I can just refill one of them and move the second to the front.
Co2 absorber is generally a safe bet.
Great video! I don't understand exactly why this method works much better than the classic one, it is clear that the media will have a much longer life, but it is not clear why the PH increases so much with this method.
Thank you! It’s rather simple actually: with refusal co2 scrubbing you’re just reducing the incoming co2 from the skimmer. With a recirculating design you allow no ambient co2 in whilst simultaneously removing the co2 produced by the tanks inhabitants.
Great video ! In the video, you show a red tubes going from the skimmer to the first canister, then the second, then back to the red tube of the skimmer, and then going back into the skimmer at the end. Where is it connected at the end ? Where is the final air without CO2 put back in the skimmer ? Do you have a kind of schematic ? Thanks !
It goes in to the silencer of the skimmer. Basically where a skimmer draws air :)
Super interesting, I'll test it out right away. My PH fluctuates between 8.5 and 8.3. Can you provide links for the hoses etc?
Glad you liked it. The hoses are from royal exclusive and the rest is from Swedish stores so won’t be of much use to you unless you are in Sweden hehe
Hi , would the extra three holes on the skimmer lid need to be blocked off to make this work correctly , like yours has carbon over them which will restrict the ambient air from entering the skimmer .
I would imagine so. Probably won’t make a huge difference but might as well.
I have installed the system as you described in my 1000l tank on my Redsea Bubble King Delux 200 RDX. How long will it take before I see some results with a higher PH ?
I notice it instantly almost
Thank you for your video. Fascinating setup and results. But, I must be missing something. The way I see your setup, your inflow air comes through those 3 carbon filled cups through the lid, then to the 2 carbon scrubbers, then to the skimmer into the reactor and collection cup. Some of the scrubbed air will be recirculated, but a significant fraction of the air in the collection cup will be 'fresh air' through the carbon filled cups. Did I get the analysis correct? Your system is scrubbing 'recirculated prescrubbed air' + 'new air'. I suppose the benefit is that the air coming from the bubbles (one can think of it as exhaled by the tank inhabitants') is rid of the CO2 at the scrubbers. But how would that be an advantage vs just venting it and bringing in new scrubbed air. Unless the 'exhaled air' has a lower CO2 fraction than scrubbed outside air. Nonetheless, the results are truly remarkable.
No, no really. It pulls through the skimmer cup in to the air intake. The volume of air will be equal so very little of any outside air will enter the system.
I have a tank of 1000 liter. What volume of canister(s) and media (Intersorb Plus ?) would you recommend ? Thank you !
3-4 liters would probably be sufficient:)
Great video! I have a different question though, hope that's ok. Apparently the Panta Rhei sponge pellets will go out of production. Do you have a suggestion for an alternative pellet? It seems really hard to find a pellet with sponge in it. Thank you.
First I’ve heard about it..that sucks. Where did you hear that? No, I’m not aware of any other pellet containing sponge unfortunately.
@@viking_reefing We have this LFS called ``Ocean and Lake` and the guy that works there was saying this. Not sure where he got his information though. I will check.
@@rositacolmenero6328 please do!
@@viking_reefing Okay, apparently Panta Rhei announced on 2021 to my LFS that they're going to stop producing. This explains why only the 250ML big size grain is still available :(
@@rositacolmenero6328 thanks for the heads up!
Sweet
Thanks!!
Are you running ozone aswell? Or if you did would you run it through the same line?
I am. I have it hooked up to the ozone port of my skimmer. The small amounts of residual ozone escaping in to the co2 scrubber doesn’t seem to effect anything.
Have you tried just using one media canister or use less media? May not need to the valve mod for your tubing then and save some $🤔
As my goal is to flatline the ph that won’t work as I will still get swings in that case.
I used the skimmer to control PH. If ph > 8.5 skimmer off. But the skimmer was off alot during the day which was ok for me because i had low nutrients already.
That would work as well but I would prefer to have it on as it helps with gas exchange

Thanks for subbing!
Hello, wonderful Reef, what are the size of the aquarium?
Thanks man! It’s 200x80x65cm so 1040L
You have the link to where you buy the material?
Unless you live in Sweden that won’t be of much use
I've been running into issues with my ph for a while now. I have a red sea 425xl. Extremely heavy coral and fish concentration. Dosing 50ml of code a&b brightwell. Equipment: reefmat, 150 int skimmer (running 24/7, brs carbon and gfo reactor, and co2 scrubber. My ph is 7.7-8.0 at best. I dont have another chamber to run cheato, however, i do have a santa monica algea scrubber( old school using air pump) im considering using that to raise nightime ph. Furthermore, i just ordered a co2 recirculator for the skimmer. Thoughts any other recommendations?
I’m thinking that since you have a lot of fish and the standard scrubber isn’t working your issue isn’t ambient co2 but rather a high co2 production from within the tank. A recirculating design should definitely help.
@viking_reefing so I obtained a recurculator for my co2 scrubber to my skimmer top with plugs. However, I've actually seen the opposite results. My ph lowered by .1 from its base. With the line off, I am getting peak 8.1 with it on the skimmer peak 7.9.
@@homebredaquatics hmm…strange. Is the skimmer powerful enough to suck adequate amounts of air through the media? You dosing restrict air flow to much with to small a hose right?
@viking_reefing most definitely it's an octo 200, and I got a recirculating top that also capped it specifically designed for this application.
@@homebredaquatics that’s very strange indeed. Flow restriction is basically the only cause I can think of
Would be nice to have some links/description of the things you purchased to make the scrubber :)
Totally get that but those links would be useless for anyone outside of Sweden unfortunately
please send them to me then 🤗
Skulle också uppskatta den infon 👍

Great video. How do you have these Angel fish in the tank with the corals?
As it’s a misconception that they eat corals
@@viking_reefing ??
No condensation getting into the co2 scrubbing media?
Nope, I have a long run from the skimmer so it hasn’t been an issue. A little bit of humidity is good as it increases the longevity of the media.
If you look at his setup the canisters are way higher than his skimmer-any condensation immediately flows back to the skimmer and doesn’t collect in his tubing or scrubber
Great video....but already ready-made available from ATI and Fauna Marin.
Actually not really. They aren’t recirculating so they will burn through media like crazy and aren’t as effective :)
How long does the media last in recirculating co2 scrubber?
About 3-4 months
@@viking_reefing that’s reasonable. Btw in my case I managed to increase my ph from 7,9 to 8,3 just by extending skimmer intake close to cabinet’s vent.
There is a thought that this method depletes oxygen in the tank. It is also very risky if you get water in the containers, as it will be pure calcium hydroxide going right in your tank, and spike your ph to the roof and kill everything.
Honestly, I think that’s just something people who hasn’t done it are speculating about. A bunch of friends have started doing it with no issues.
Yeah, that risk has to be mitigated. I tried filling up my skimmer cup with water to see what would happen and the draw isn’t enough for the water to make it to the containers.
Any problems with your angels and idol eating your corals?
Nope. They pick but it’s not an issue
Nice idea, but didn't work out for me. Back to the hose with outside air 😊
It will depend on how your co2 is introduced. My main contributing factor is the fish inside the tank. Ambient co2 is very low as I have a very effective full house air exchange unit.
What media are you using?
Intersorb. I bought 25kg of the stuff in bulk. Gonna last me a lifetime haha
So easy, put smashed coral in a net and put it in the sump, u gotta put a bunch in a small tank but more if u got a big tank xd 😊
