Overflow noise in Marineland 60g cube

[ravenjred]

Does anyone know how I can stop the noise in my overflow in a Mainland 60g cube. I have a corner overflow and the noise is coming from the water going into the overflow and hitting the water below. The water level in the overflow is about 3" below the water level in the tank. Very loud and annoying. Thanks.

I have a T PVC fitting on my drain, then a 90 degree facing back down in the overflow (obviously at water height) then a small piece with a cap at the top of the T with a hole drilled into it and mine makes ABSOLUTELY NO NOISE WHAT SO EVER. And it's next to my bed.

Below is a picture so you can see it.

Among other things, too much flow can also make a drain excessively noisy.

Something to consider if you are returning more than two to four times your display's volume per hour from the sump. (120gph-240gph - all that's generally needed for a 60g.)

I'm having a similar problem . I have the 93 gallon version of the same tank and I keep getting a " slurping noise " from my overflow . Mine had a 90 at the top and the turns down . Well the 90 has a pre drilled hole in it and as the water level raises and lowers in the return chamber it will make the noise if the water level gets close to the height of the pre drilled hole . Any ideas ?

Change the 90 to a T with a small piece of pvc extension with a cap drilled with at least a 1/4-3/8" hole for more air. Just like mine. Mine made a surging noise once I made the hole bigger and no problems since.

Awesome man thanks . Ill give it a try .

Turns out that my problem was that my return pump was way too strong. I switched to a smaller pump and WALA!, no more noise. I hear just a little bit of the water flow and that is all. Finally!!! I can now concentrate on hooking up my electrical and getting my tank cycled.

Sweet! Sounds like great news Ravenjred!

Well I might be having a noisy tank cause I'm gonna run 1200gph on my 57 gallon

Some people have a reason/requirement for doing that and some people don't mind the excess cost/noise. YMMV

But I also do not have an overflow I drilled the tank myself so might get lucky and still be quiet

Most overflows and interior drains are built on 1" plumbing and will pretty much share performance qualities.

If you make the drain plumbing larger (even if doing so requires an adapter) it can help. In general, no matter the size of the drain, exceeding 50% of the drain's rated flow will lead to noise, excessive air-mixing and possibly other issues. For something like 1200gph (enough flow to drive the filtration for a tank between 300 and 600 gallons...a waste on a smaller tank) you'd either want something like a Herbie drain that uses multiple drain pipes, or you'd want a significantly larger diameter for your drain pipe.

Yes and I am running two 1" drains for the 57g and one of them will remain a full syphon so hopefully not much noise and the second is water level/ emergency drain if syphon gets blocked
