Hi all,
Recently I got back into aquarium setup and got a 80g tank.
Filtration system is a overflow with backup going to a sump. (Similar to image attached)
The overflow pipe has a ball valve and I am trying to control the flow and quiet it down.
I can either achieve one of the following:
- noisy, max flow, sump return pump won’t go dry. Happy day but noisy tank
- quiet, controlled flow by ball valve, sump return pump will eventually dry up and overflow box will fill up slowly
I have done some research but ran out of idea unfortunately.
What have I done so far:
- fine tune ball valve but overflow box level will always increase ever so slightly and return sump dry up (tried many days)
- built a durso and installed over the overflow pipe unfortunately it was as noisy
- stick a small pipe into the middle of overflow pipe, this actually quiet it down due to reduce in air
- reduce rate of return pump but no luck
What I believe is:
- noise is coming from the air (gap) of the overflow pipe, I can Cleary see air bubble at the sump
Also included video of the current overflow and sump below:

Sorry for the long post but I ran out of idea
Thank you
