It sounds like cavitation, this is caused by a number situations in the world of hydraulics. 1) low pressure on the suction side. 2) Possible sharp 90 degree bends 3) Something simple like a dirty pre filter restricting flow on suction side. 4) A basic imbalance of water in and water out, can cause cavitation. My thoughts, clean the pre filter and KEEP IT!! Next, experiment with a "sweep" or gentle bend on your suction intake and see if this takes care of your "cavitation" issue. Try a more coarse pre filter. Yes, it is possible to have a slight suction side leak (air sucking in) and do not use Vaseline, I prefer "Lube Tube" small tube 1oz. Please use very small amount of lubricant on o-rings and gaskets. I hope this helps. Also, thank you for taking the time to make these videos, as you have helped me many times!! :-)

Oase did a facelift on biomaster. The prefilter pipe wasn’t drilled enough. The new pipe is drilled on every side and the holes are bigger. For them, it’s a way to reduce the noise. However some people still have the issue apparently. Might be better to have the lowest ppi foam?

Someone alreary mentioned Pondguru and how he optimized this filter by drilling more holes to the prefilter pipe (he actually replaced the original pipe with a new one, maybe you want to do the same so you don't lose the guarantee). Liquid Nature have also made a video about drilling more holes to the prefilter pipe ("Oase BioMaster Vorfilter Tuning"). I don't know if you can speak German, but there were many comments saying that they had done this also, and it should really help with the flowrate. Hopefully that will in turn also help with the noise problem/air bubbles.

@@itsokay7989 I am no expert either, but I would think that IF the air bubble problem is caused by some kind of pressure/underpressure issue, then this method is only going to help. Many people have done this modification and I haven't seen anyone saying that it would have caused problems (well one person said that he had priming problems after it, but was it because of this modification, because no one else had similar issues). But this is why it is best to not drill the original pipe, but use a new pipe (like Pondguru did), so if there would be any problems/side effects you can always go back to using the original pipe.

Today I purchased a new filter Oase BioMaster 850 for 120*45*45 tank. Also i am using Shiruba XB-312, which is an excellent filter, I have been using it for 5 years. Till now there are no issues and sound is completely silent. After unboxing the new Oase BioMaster 850 filter, i saw the main problem, that there is no lubricant applied for seals, which is the main cause for sound and bubble issue. In shiruba all seals were lubricated but in this it's dry, which can cause further leaking, sound and short life of seals. So I applied vaseline for rubber sealings. Now it's working great with low noise.

@ArsenicShooter 6 ай бұрын

I would recommend you to use silicone for the gaskets, because vaseline (petroleum) destroys the gaskets with time (at the beginning it seems better but after one year it may break and leak).

I never had issues with my 350. Still havent in 3 years or so. But my 600 and 850 purged a lot of air all the time and than they where noisy. I had contact with Oase and they replaced the pumpheads of my filters. This helped with my 600. But i still had issues with the 850. Than i added clamps on all the tube connections and replaced the oase pipe set with Stainless steel ones without a skimmer. And than it was fixed. No air purging. So my guess is they suck air through the connections somewhere. Not sure where cause i did all of it at the same time. Cause of the Pond Guru video i allready made lots of extra holes in the tube of the pre-filter. No problems now.

@SklepKoszykarski 2 жыл бұрын

Another solution is to keep the sponges, but drill more holes in the pre-filter tube. You can drill them in a straight line so that they cross each other. So You will have better flow even with sponges. I have Oase too, I raise my bubbles, at the end of the day, I stopped getting attention, but I saw this idea in one of the KZfaq stores and it wasn't long to do.

You should seriously consider using a bypass for the CO2 reactor. The manufacturerers of (large) CO2 reactors often recommend a maximum flow of 200-300 l/h going through the reactor to eliminate noise and maximize CO2 dissolution. But you will need a bypass to achieve this flow rate. The bypass will also increase the filter's output due to the reduction of pressure. Note: I have a BioMaster 600 (rated 1250 l/h), with additional holes on the pre-filter pipe, connected to a CO2 reactor and UVC using a bypass and I manage ~800 l/h of output without noise. So, if you are only getting 600 l/h with the larger BioMaster 850 you do have flow constrains in your system.

I’ve never had any big issues with any of my bio masters but I have had some noise from one. That was my own fault when doing a water change I messed up some how, but it has been fine since. I also think the flow situation could be because the flow stated by oase is the flow you get with only the supplied sponges inside, and because we obviously add other media to it, it slows the flow 🤔🤷🏽‍♂️ (Noise levels in my living mostly get drowned out by the air pump for the tanks that don’t have biomasters 😅)

So, by this video you explained what i suspected with my own filters. Not Oase, other brand. I noticed that when the intake is clogged, the pump would create negative pressure inside the canister. Since it couldn't draw more water (restricted flow), it would suck air from the outside... Mystery solved. 😀

I have the same filter, and for me the solution is easy. Make the outflow longer then the inflow. The tube of my outflow is twice the length of the inflow and it is dead quiet. Also I do not use the original intake and outflow parts, but have my own, maybe that also has some impact as well.

People online seemed to say air can get trapped inside when you do water changes. My intake has a surface skimmer so maybe air got in through the top of it when the water level was low. Thank god that’s all it took to fix it lol. My tank is in my bedroom and the sound was so concerning. Nightmares of waking up with water flooded on my floor or something.

@AmyLuthien 2 жыл бұрын

There is one other thing to be mindful of when maximizing your filter's gallons/liters per minute and that is the intake and outlet hoses to/from the filter. If they haven't been cleaned in a while, it will significantly reduce the flow. I have one aquarium with a wer/dry filter, and if the hoses are not cleaned out, the flow is reduced enough that air bubbles will get trapping in the overflow siphon tube to the point of breaking the siphon entirely and stopping all filtration. Once the hoses are cleaned out and that fine layer of biofilm that builds up in all hoses over time is removed, everything runs exactly as it should. Another aquarium I have has a canister filter, lily pipes etc., and has similar problems with reduced flow if I don't take those hoses off and clean them once a month or so. I do not have a canister filter with a pre-filter option on it, but it might be worth a try to clean out the hoses, then put the pre-filter back in and see if that eliminates the "burping" issue.

@tiberiuminzu3270 2 жыл бұрын

I have a bio master 600 on a 90p tank - I agree that the burping can be annoying, typically it will burp 6-10 times an evening. But I believe I get this from air entering the skimmer intake and more so after water changes - I knock the sides of the filter if it continues. On the other hand having the prefilter is great (especially if you have leaf debris floating up) and the flow is good (even a little strong) so I think it’s a worth while trade off.

Hello MJ. I have the same biomaster 850. Have the same problem of noise. Have done many experiments on it as why it’s noisy. It’s because of filter media. Some filter media are light weight and floats in water. Using such filter media in filter causes air noise. Make sure your filter media is heavy weight. Like I was using some sort of stones which are very light and was not sinking in water it was the cause of noise. I changed the media and all set filter is working very well now. Hope this will help everyone who has noise in the filter. Please do not use filter media which is very light weight and won’t sink in water.

Yes i followed Pondgurus advice to drill more holes into the prefilter and got the more course sponges...but even then i had no issues with bubbles building up before that. I also used fine mesh intake covers cause of my shrimp so all this wasnt an issue... What had changed? My filter intake and out werent at a 90 degrees...they were tilted a little, the outflow leaning into the plastic tank and the intake leaning out in a 20-30 degrees. In my opinion...since now that my filter is back at my bigger shallow tank and the outflow and intake are properly adjusted again there are no more bubbles. So a tilted intake or outflow might cause the bubbly issues.

Keep in mind that if you have restrictions on the discharge side of the pump, they will also affect the flow coming into the filter. So the reactor can definitely restrict the overall flow. If a pump needs to overcome restrictions on the discharge side, it needs to put in more work to overcome that and keep the same amount of flow through the whole system as without restriction. Since the power of the pump is fixed, the restrictions on the discharge do affect the flow as well.

So this is of course true. Limiting output will limit input - water is incompressible and it has to go somewhere, but doesn't really address the purge issue. If the flow is equal on both the inlet and the outlet then the filter is operating as designed. However, if there is an imbalance then the water level inside the filter will change. If the inflow is greater than the outflow and if the water has no way to vacate the filter (i,e through a leak) it will back up into the intake in order to maintain equilibrium, reducing overall flow rate. If the intake is less than the outlet then a vacuum is drawn, and the water level will decrease, drawing in air around the gaskets and seals, as is hypothesized here. Running it this way is probably hard on the gasket and seals, and puts greater load on the impeller. If the inlet is being restricted, and the vacuum in its place is the source of the bubbles, limiting the outlet proportionally to the resistance seen on the inlet should help at the cost of the overall flow rate. My guess is that adding a flow control valve on the outlet might solve the issue.

You can try to do what pound guru on Yt shows, he drilled more holes in the intake pipe in the prefilter

Zoals je weet, Filter opbouw begint met sponsen van grof naar fijn, (en daarna bio en daarna evt chem filtering) als je van die grove blauwe spons sponsen voor de prefilter knipt en je boort minimaal 2x zoveel gaatjes in de buis die in het prefilter zit is het opgelost. Maar beter nog je zou ook een iets dikkere buis in het prefilter kunnen zetten waar je de gaatjes zelf in boort je steekt de buis er dan niet in maar doet hem er overheen. Je zou een plastic dopje van bijv een 1/2 ltr pak koffiemelk kunnen gebruiken om de buis af te sluiten of prop er een stukje filterspons in die zeer strak zit. De impeller maakt ook een stuk minder geluid als je het staafje en de rest er van met een filmlaagje vaseline insmeert. Dit is zo ongeveer hoe ik het opgelost heb.

Das liegt nicht direkt am Filter! Dieses bekannte Problem bzw. Phänomen tritt auf, wenn man zu viel an Druck oder Saugseite installiert und somit eine gewissen unausgewogen Unterdruck erzeugt! Dann zieht er durch jede erdenkliche Ritze Luft! Das kann auch passieren, wenn der Durchmesser von Lillypipe, Schlauch etc., auf der Saugseite kleiner ist als auf der Druckseite!

Hey Man, I had the same issue with mine, i even sent it back for testing, turns out it doesnt like having too much droop in the hoses. I discovered this after setting it back up with a new(taller) stand. It now has a more vertical route to the inlet and outlet. I get absolutley zero noise now and this was coming from a filter I was ready to discard because it was so annoying.

@andyh126 2 жыл бұрын

100% correct! I too reduced ‘droop’ to zero by shortening hoses and now makes no noise. Also increased number of holes in pre filter pipe.

Have you tried to put the external filter in a styrofoam box? I never tried it, but maybe, if put vertically, you can make holes for the pipes and cable and finally close the cap (if you have put it vertically, it should work as a door), it should insulate a bit

Hi MY I did comment when you initially reviewed this filter that having watched reviews on the Oase and the Aquael 2000 I opted for the latter. I commented on how quiet the filter was and having run it for 6 weeks now I am delighted with my choice. In general of is whisper quiet and you only hear the faintest him when there is absolutely no other sounds in the room, even the clock is louder. A 2000 litre per hour is theoretically much too big for my 125 litre tank but I have packed it with an array of filter media and still need to throttle the flow to stop it redistributing the substrate. I am confident that once the foreground plants grow a little more I Will be able to open the flow up more. Perhaps you could try one yourself and give us all a direct comparison and see if you agree with Pondguru?

There is an other opportunity to update the filtration flow: modify the prefilter tube with a bigger one (20 mm of internal diameter) and drill extra holes on it. With More holes, with a bigger tube the filtration will works much more properly. What do you say about that?

And the noise in the Biomaster 850 originates from... the Juwel stand. (like you have here) The Juwel stand looks nice, but has a number of design flaws. First of all, it has an open backside where you put the pump. Somehow logical, but the open closet becomes a resonant box. Any noise is amplified, in particular the low frequencies. You can reduce that using acoustic foam and closing the backside as much as possible. That did help somewhat, but the best solution in the end was to take the pump out of the closet. For reasons of strength the stand has 3 segments. Great, but the Fluval FX4 doesn't fit in it. The material is also such that one a hinge is broken you can't repair it My conclusion: the Biomaster 850 is silent enough, it's the design of the Juwel stand
