The point of drilling more holes is that the prefilter sponges are used more evenly, so the flowrate stands more stable over a longer period of time even when it’s starts clogging
Yes drill more holes in it. No, don’t make them bigger to increase flow, cus it wont increase flow. Instead what this does is allows water in through the pre filter at the same rate out the outlet. This resolves the constant choking of the Oase filter. No more burps or bubbles :)
As it happens, I set up a BioMaster 350 on a 40 gallon breeder just last night. For my purposes, the flow is excellent. Even with the spray bar set one inch below the water line, it agitates the surface well. And the filter itself is silent as a stone. But I think you were right in your first video: if you want higher flow, you have to go with the 600 or 850 model (or with a different make). I don't think there's any pimping the piping or tubing to raise flow. And I personally cut the manufacturer's reported flow rate by half.
I run several 600 series. Tank sizes 25g, 30g, 40g. Anything larger Ill either run two or a single larger filter such as the eheim 2260. Cant be overstated, go as big as possible.
Awesome scientific test done!!! Such a great test, really can feel the hard work going in, controlling the variables well. Really appreciate such clear and unbias review.
I think the additional holes in the pre-filter pipe helps it solve some trapped air bubble issues I see some RUclipsrs are facing. I don't think it'll increase the flow rate.
Not only that if the pre filter it self gets plugged up the water don't have to make a big go around so it keeps working longer before the flow gets reduced
Thanks for your testing. You confirmed what a lot of us suspected, Pondguru is just making things up and filter manufacturers' engineers have already optimized these units.
For a discus tank low flow and huge media is pure gold of a filter. I run 2x850s (to always have a backup running in case if failer) + a cleartronic uvc 11w on a 400l discus tank and my water is crystal, discus swimming in the air !
I also have 2 850s running on a 167gal for discus. Looking for uv options? Are you happy with the cleartronic? And are you running it off one of the 850s?
I used to promote the idea of drilling more/bigger holes until I spoke to an Oase rep, the pipe as it comes is suitably drilled for the pump head. Adding more holes will make no difference as the pump and media is the restriction. If you want more flow upgrade the head.
@@chrisrabatin625 the heads are interchangeable as the diameters are the same between the 250,350 and 600. You can put the 600 head on a 250 canister or if you wanted less flow you can reverse. One of the only things you would have to keep is the prefilter from the smaller sized canister as it’s the depth that changes in an extra tray as you go up/down in size. The only one I’m not sure is the new 850 as I’ve not seen one to measure it but I’d assume the footprint is the same as the rest in the series. Obviously you may be hindered by heater depth too so you’d have to look up lengths on Oase’s website www.Oase.com
I think if you get off completly the pipe you take the maximum possibilities to upgrade the flow. If test this and didn't increased the flow this means that the flow reduction comes from and other spot of filter and no needs to experiment with the pipe. Good job keep like this 👍👍👍
Thanks for sharing these results. I still prefer oase filters for the built in heater and easier maintenance on account of the prefilter sponge. Considering the heater is included in the price they are a great value in my opinion. I'm using a 250 on a 20g long and the flow seems fine to me. For future tanks I'll just use an oversized oase canister or double up on them. I am tempted to try a super jet one day but sucks to lose the heater in the filter and I prefer to avoid submersibles.
Oase is def my top go to for filters. I use the off brand superjet from Fzone lol. Maintenance is a bit annoying without trays but pump adjustment and other things makes up for it. It all comes down to personal preference.
Basic fluid dynamics, only so much water can flow through a given diameter. Unless you change the size of every orifice in the water path you are not going to increase the volume of water that can pass through the smallest opening it the water path. you could remove the pre filter tube and it will not increase the gph. Most videos on this topic are wrong. You can reduce the flow with a restriction, like when you hold your finger over the end of a hose, the water will shoot farther but the flow rate will be reduced. You might be able to increase gph if you could install a different impeller (probably can't) and I am assuming the openings throughout the filter are matched to the max flow capabilities of the motor.
Guess I could be way wrong about this but my opinion on canister filters or any type of aquarium filter is the amount of media it will hold is the key to good water quality. I don't want a whole lot of turbulence in my tank no matter what's in there . I do want a lot of media for the water to pass through . what I believe is the longer the water is interacting with whatever media you are using the better filtering you are going to get. Like I said I could be way wrong but I have had fish since I was twelve years old and I still have fish at 74 . Remember blowing water through whatever you use in your filter does not mean quality water coming out.
Did you try setting the filter at a different height to the outflow? I suspect the manufacturer flow rate assumes the tank and filter are sitting side by side at the same height. Having the filter beneath the tank means it has to push the water to at least 1 metre height against gravity, which may have a slowing effect on the rate of flow.
Interesting - thanks for the tests. Just bear in mind that "head height" significantly changes the efficiency of a pump. The manufacturer's rating will be with no media and the pump at the same level as the inlet/outlet to the tank. For future testing, you should stick to the zero head height for standardization purposes. People are always cynical about manufacturers, but to be fair they have to practice standardization in their testing conditions, and given that everyone's setup is going to be different, what better level to use than zero as the standard? On a related point, head height and flow rate are never a fixed relationship when comparing different pumps. You can get pumps that can create humungous amounts of flow but have a terrible head height rating - and vice-versa. Cheers from South Africa.
I purchased the Biomaster 350 last December for my 90 gallon. Love the design and construction, but disappointed with the dismal flow rate. I have a Marineland 360 on my 55 gallon and it has a more powerful flow rate and cost 1/2 the price of the Oase. I have taken down the Oase and replaced it with a SunSun 304b, which costed me 1/3 the price of the Oase. I do not known the long-term durability of the SunSun, but I can honestly say it’s powerful, easy to setup & prime. I purchased a 2nd SunSun 304b as a backup since it was so inexpensive.
Hey there, I have a suggestion. After watching your video. Has anyone ever tried taking out the impeller and replace it with a bigger impeller? Then run a test on the flow rate again on the Oase filter.
The hose size and the distance will still be the same so technically a a higher gph will be negligible even if this idea works in theory. Check out my latest videos on the Fzone stainless steel canister filter.
Drilling holes assumes that the pipe is a bottleneck. Changing/removing media assumes media is a bottleneck. It could be there is no bottleneck. The limitation is ultimately the pump itself.
@@TankTastic 400 l/h - 105 US galons for an Oase Biomaster 350. I changed a sponge tray with 1 litre of Seachem Matrix, and the upper tray is full of Eheim SubstractPro (1/4 litre) instead 30 ppm sponge. Poor flow so far...
hello i'm korean. oase biomaster 350, this product is selling for $396 in Korea. Note that this is a product without a heater. And the eheim professinel4 600 is $362 in Korea. In Korea, canister filters are ridiculously expensive. Which of these two would you buy?
I went the 250 route for my 40 gallon breeder and the agitation is okay but flow is horrible. I hear you can just swap the head unit from a bigger model to get the rate you want, but not recomended. Idk I may just upgrade and use the 250 on my daughters 10gallon tank or something. I would like to add the frustrating part is when I see particles go near the inlet and pass by it. definitely go 600 or better.
Here's the thing though... all the competitors are showing the same discrepancy vs their specification. Sometimes I wonder if that 5x per hour number was developed with that in mind. I picked up a thermo 600. Currently cycling it on an older tank while I put my new tank together. I think the benefits of the prefilter and built-in heater make the flow rate reduction a reasonable compromise. Especially considering this dishonesty is rampant across all manufacturers.
This is why i stayed away from the Biomaster. I was looking into it due to its pre-filter and the build quality. But i was going to used it to push through a Chiller. From the reviews I've seen is that the flow really is a bummer. For its price i dont want to do any modification as it may void the warranty. Thats why I opted for the Aquael Ultramax 2000. With filter media the flow rate is 1000lph or 264gph.
yeah looking forward on your review on that one. not many English reviews on the Aquael. Good job on the honest review on the Biomaster. Not many youtubers talk about the flow issue of the Biomaster. Keep it up bro!
I also ordered the pipe again in case something goes wrong and drilled more holes...also what made a little difference was going for the more course filter sponge you put onto the prefilter unit, the orange ones. I didnt measure it but the outflow was better in my opinion...though it didnt have a big impact overall but that little helped. I run it on a custom made tank with nearly 200L and its enough...but i didnt want a strong flow so thats fine. What irritates me the most is the big rain pipe...with one pipe the flow is fine if i add the second water barely comes out of it which just feels weird if Oase tested it and thought thats enough. Its not! Dont include the second rainpipe cause its useless lol an it still feels weird that you have to make some changes to a Filter you buy to make it...better. A company should have enough experience to correct minor issues like this before they release it, or at least sell new Filters with this in mind and make those changes that just help the filter in general. somehow it feels like companies never look at feedback of their products as they have thjeir own youtubers they send it too and most of them just praise a product no matter what...or ofc they go for 2 Filters for a setup which is pretty pricy and not everyone does that.
Yea man, I totally agree. I use the orange 30ppi prefilter sponges now. Someone commented in the last video about using 10ppi so that can help too. I feel like these filters are good for fish keeping, but I don’t think anyone thinks about heavily planted tanks. So they create a product thats like in-between to satisfy a universal customer base. But yea, I personally will get a powerhead for my setups.
@@TankTastic i wish they would give you a choice when you order them which kind of diameter prefilter pipe you want and how course the sponges will be...or like deliver it without them and make it a must extra option what else you must pick in addition to the filter. I like how quiet this filter is but maybe the AQUAEL Filter ULTRAMAX 1000 with prefilter for nearly half the price is the better option, its only missing the heater but is as quiet as this one, little less prefilter chamber but for near half the price looks like a better option right now.
Thats actually a dope idea, we in 2021 customization is everywhere. Lol i wish someone did that. Im in NyC I had a hard time finding the ultramaxx, I def want one though.
@@TankTastic I found it on amazon^^ might be easier over here at germany/europe...i got the 350 for a cheaper price and if i bought a heater for the Ultramaxx it would have been a 10 bucks difference so i went with Oase. But yeah customisation would go a long way...looking forward to the new skimmer for the filter outflow so i can remove my ugly grey eheim one...yeah it wont suck in the gunk but it wont have the danger of sucking in my fish or shrimp and dying
The reson your only getn about half the amount of flow u should is cause the higher the water gets pumped up lowers the flow it comes down to head pressure try having the filter higher but still under the bottem of the tank and it should improve a lot but to do this you need to cut the hoses shorter
Late response, the filter is as high in the cabinet as possible and the hoses is the shortest I can get it. A shorter cabinet may help based on your comment.

¿Has medido por casualidad el consumo eléctrico del filtro? Según la casa Oase es de 18W pero mi Biomaster 350 consume sólo 10W aproximadamente. Un saludo
Great video, did you ever pursue putting a bionmaster 600 pump head on the 300 canister? I was led to believe the heads fit on? I emailed Oase US and of course they said they don't recommend it as "Each filter head is uniquely designed for each canister size". But some other folks I trust say they have done it.
I was thinking the same even putting a 850 head on top. I have seen places where it's possible to buy spare parts. How is the experience from the people you know? Did they get a bigger flow rate?
Maybe the rotor of a biomaster 850, fits in a 350. Then we go from 3 blades to 6 blades. It looks on the picture like the same size, did someone came up with this idea and tryed it?!?
The Pond Guru/Pimp My Filter video that people referred you to doesn't actually mention any flow rates, nor perform any tests or cite any research or even personal experience to suggest one will achieve A higher flow rate with his modifications. He just said the standard pipe was too restrictive & he could improve that so he changed it. That does make sense as you mentioned. He actually never tests or claims to have tested the flow rate prior to or after his modification. Nor does he provide us with any data to suggest any improvement in flow or suction was achieved he states it as fact. For all we know, based on his video, there may not have been any change in the GPH at all after his modification but only the assumption of improved flow rate based on said modification. It would appear your own testing bears this out. I have nothing against the Pond Guru & his videos have helped me personally improve my filtration systems over the years. I understand his logic, but I'm not convinced his modification of the prefilter pipe in this filter is as valuable as people think it. Once again, your actual test bears this out.
@@TankTastic I believe you. Why would the flow rate increase by making tubes wider with more holes? Think of placing your thumb over a garden hose to increase the pressure. This works by forcing water out of a smaller area, not larger, yet the GPH remain the same.
@@TankTastic I'm not sure that would even increase GPH. You would need a more powerful motor to move the water faster to increase GPH. You can force water through a smaller tube to increase pressure but not GPH. Like placing your thumb over a running garden hose.
Increased power dont help. Check out my video with the Fzone stainless steel. It has max output of 800gph. IMO, whats holding the GPH back is the 16/22 hoses. Bigger hose, more water is able to flow through. But unfortunately, hose size for this hobby max out at 16/22.
I guess the last thing you could do is to put your filter in a higher place and cut your hoses as short as possible. I mean, there are hoses, they don't cost much money. So, that is my last recommendation. But just remember not to put your filter at the same level of your aquarium. Is recommendable to keep your filter under the tank.
Yea, that would be but based on my stand and the height of it. This is pretty maxed out. 😢 I would have to get a shorter stand or put the filter outside sitting on a platform.
@@TankTastic Oh, It's not really helpful ☹️. You know what?, Maybe the user manual of the filter says something about high recommendations. I saw that in my fluval filter, if your filter high is between the ranges, then the problem is the brand☹️. You know, these filters have a very good quality, talking about the design and the filtration, but maybe they don't worry about the flow rate
@@TankTastic how much Seachem would I need to buy for the 600 it’s says 500ml will do 200ltrs my tank is 165ltrs should I just get loads like 3ltrs off the stuff and fill up 3 Trays
They are rated for flow right at the connection point .. you weren't trying to pull flow up where you ? If so of course the flow will go way down.. the filter was designed like it was for a reason .. your not going get more flow by running a large pipe restricted into a smaller one .. anyways water turnover into a filter is way overrated .. you should be buying a filter rated 2 times the size the company suggest imo just for.the filter capacity I use bottom tray sponge 3 trays of matrix and then carbon and use 2 nano Nero's in the tank .. this is coming from someone that runs a med to heavy stocked 29 gallon reef tank with a biomaster 600 and 10% water changes every week basically what I get out from cleaning my sand .if I was running something like 100 gallon I be using something like a biomaster 850 maybe even 2.. for saltwater tank owners if you can't do weeky maintenance you shouldn't be in the hobby .. when I go on vacation for more then a week I pay a maintenance service to come over ..to many people just want something with no effort .. it be like owning a dog and not taking it for walks daily it's plain abuse simple as that .
If you put a larger pipe in the pre-filter, or drill holes in the factory one, It’s like changing a 2 lane highway to 2.2 lanes for 1 mile on a 10 mile highway. The majority of the road is the same.
The point of drilling more holes is that the prefilter sponges are used more evenly, so the flowrate stands more stable over a longer period of time even when it’s starts clogging
I agree
Yes, that's what I thought and why I drilled some additional holes in my 600 pre-filter tube. So I believe it is still worth doing ....
I don't believe in that.
You turned bro Science into actual science. These guys are engineers, they don’t do things by accident. Great video bro.
They have a new pre filter tube that is a dark grey color with many more holes and it has a bigger inside diameter than the old clear tube.
Yes drill more holes in it. No, don’t make them bigger to increase flow, cus it wont increase flow. Instead what this does is allows water in through the pre filter at the same rate out the outlet. This resolves the constant choking of the Oase filter. No more burps or bubbles :)

Thats actually a dope idea, we in 2021 customization is everywhere. Lol i wish someone did that. Im in NyC I had a hard time finding the ultramaxx, I def want one though.
@@TankTastic I found it on amazon^^ might be easier over here at germany/europe...i got the 350 for a cheaper price and if i bought a heater for the Ultramaxx it would have been a 10 bucks difference so i went with Oase.
But yeah customisation would go a long way...looking forward to the new skimmer for the filter outflow so i can remove my ugly grey eheim one...yeah it wont suck in the gunk but it wont have the danger of sucking in my fish or shrimp and dying
They'll do it so u buy a filter thinking ur getn 300gph n find out its 150 ngo buy there bigger model not knowing ull go for a different make
The reson your only getn about half the amount of flow u should is cause the higher the water gets pumped up lowers the flow it comes down to head pressure try having the filter higher but still under the bottem of the tank and it should improve a lot but to do this you need to cut the hoses shorter
Late response, the filter is as high in the cabinet as possible and the hoses is the shortest I can get it. A shorter cabinet may help based on your comment.
¿Has medido por casualidad el consumo eléctrico del filtro? Según la casa Oase es de 18W pero mi Biomaster 350 consume sólo 10W aproximadamente. Un saludo
Great video, did you ever pursue putting a bionmaster 600 pump head on the 300 canister? I was led to believe the heads fit on? I emailed Oase US and of course they said they don't recommend it as "Each filter head is uniquely designed for each canister size". But some other folks I trust say they have done it.
I have not, I moved so my tank is down and havent gotten to it yet. But most likely not, a power head is a cheaper solution lol
I was thinking the same even putting a 850 head on top. I have seen places where it's possible to buy spare parts. How is the experience from the people you know? Did they get a bigger flow rate?
@Tomáš Marcinčin hey, not yet.
Maybe the rotor of a biomaster 850, fits in a 350. Then we go from 3 blades to 6 blades. It looks on the picture like the same size, did someone came up with this idea and tryed it?!?

Do you have a link to the video where he shows what pipe he bought to replace the intake pipe?
Or do you have a link for that intake pipe?

The Pond Guru/Pimp My Filter video that people referred you to doesn't actually mention any flow rates, nor perform any tests or cite any research or even personal experience to suggest one will achieve A higher flow rate with his modifications. He just said the standard pipe was too restrictive & he could improve that so he changed it. That does make sense as you mentioned. He actually never tests or claims to have tested the flow rate prior to or after his modification. Nor does he provide us with any data to suggest any improvement in flow or suction was achieved he states it as fact. For all we know, based on his video, there may not have been any change in the GPH at all after his modification but only the assumption of improved flow rate based on said modification. It would appear your own testing bears this out. I have nothing against the Pond Guru & his videos have helped me personally improve my filtration systems over the years. I understand his logic, but I'm not convinced his modification of the prefilter pipe in this filter is as valuable as people think it. Once again, your actual test bears this out.
It does absolutely nothing
The only way to get more gph is to get a bigger hose for your filter, bigger than 16/22mm.
@@TankTastic I believe you. Why would the flow rate increase by making tubes wider with more holes? Think of placing your thumb over a garden hose to increase the pressure. This works by forcing water out of a smaller area, not larger, yet the GPH remain the same.
@@TankTastic I'm not sure that would even increase GPH. You would need a more powerful motor to move the water faster to increase GPH. You can force water through a smaller tube to increase pressure but not GPH. Like placing your thumb over a running garden hose.
Increased power dont help. Check out my video with the Fzone stainless steel. It has max output of 800gph. IMO, whats holding the GPH back is the 16/22 hoses. Bigger hose, more water is able to flow through. But unfortunately, hose size for this hobby max out at 16/22.
It seems obvious the problem isn't restriction, as you've proven that. That only leaves the pump itself isn't going to produce any more flow.
I guess the last thing you could do is to put your filter in a higher place and cut your hoses as short as possible. I mean, there are hoses, they don't cost much money. So, that is my last recommendation.
But just remember not to put your filter at the same level of your aquarium. Is recommendable to keep your filter under the tank.
Yea, that would be but based on my stand and the height of it. This is pretty maxed out. 😢 I would have to get a shorter stand or put the filter outside sitting on a platform.
@@TankTastic Oh, It's not really helpful ☹️.
You know what?, Maybe the user manual of the filter says something about high recommendations. I saw that in my fluval filter, if your filter high is between the ranges, then the problem is the brand☹️.
You know, these filters have a very good quality, talking about the design and the filtration, but maybe they don't worry about the flow rate
Yea I dont think they do, filter is def good. But its a universal filter and some ppl dont want crazy flow
Hi can I ask you what filter bio media do you use as I need to get some for my oase bio master 600 thanks
Seachem Matrix mainly, I also use ceramics and eheim media.
@@TankTastic how much Seachem would I need to buy for the 600 it’s says 500ml will do 200ltrs my tank is 165ltrs should I just get loads like 3ltrs off the stuff and fill up 3 Trays
@@domesticcardetailing8295 well max for the 360 is 5.6L. Maybe get two 4L buckets, always nice to have extras
They are rated for flow right at the connection point .. you weren't trying to pull flow up where you ? If so of course the flow will go way down.. the filter was designed like it was for a reason .. your not going get more flow by running a large pipe restricted into a smaller one .. anyways water turnover into a filter is way overrated .. you should be buying a filter rated 2 times the size the company suggest imo just for.the filter capacity I use bottom tray sponge 3 trays of matrix and then carbon and use 2 nano Nero's in the tank .. this is coming from someone that runs a med to heavy stocked 29 gallon reef tank with a biomaster 600 and 10% water changes every week basically what I get out from cleaning my sand .if I was running something like 100 gallon I be using something like a biomaster 850 maybe even 2.. for saltwater tank owners if you can't do weeky maintenance you shouldn't be in the hobby .. when I go on vacation for more then a week I pay a maintenance service to come over ..to many people just want something with no effort .. it be like owning a dog and not taking it for walks daily it's plain abuse simple as that .
I run 2 Biomaster 250’s on my 50 gal freashwater. One is strictly filtering and the second is set up with bcb bags
If you put a larger pipe in the pre-filter, or drill holes in the factory one, It’s like changing a 2 lane highway to 2.2 lanes for 1 mile on a 10 mile highway. The majority of the road is the same.
Meant pre filter sorry spell checker got me 🙂
