How to reduce overflow / plumbing noise?

[steve9k]

Still in the process of setting up my tank -- attached all the plumbing, filled it with RO/DI water, ready to add salt. Just a slight problem with noise.

The tank is a 75g AGA with built-in overflow box. I have 1" PVC pipe carrying the water from the overflow into the sump, where it discharges below the water level. So, I've eliminated any splashing noise. BUT, the sound of the water flowing thru the pipe itself is very noticable, and once in a while I hear a gurgling sound, like water going down a bathtub drain. I *think* this could be due to air coming down the pipe (bubbles come out the discharge, usually small with some fat ones interspersed).

Any suggestions on how to cut the noise down?

Try out a Durso Standpipe. http://www.dursostandpipes.com WAY easy to make out of CHEAP pvc materials. Check out the "popular modifications" section to see which one would apply to you.

I have 2 stockman hangon overflow standpipe... Ken's version. Cost about $4 total, absolutely silent.

I used the setup from the following link and so far so good.

Take at least a 1' long piece of air line tubing and stick it down the over flow and leave it sticking up out of the top. This should help...
