my tank makes alot! of noise! its hard plumbed with 1 inch PVC that runs under the water in the sump! i got no pics!
the durso is just a tee with a cap and a hole drilled in it on the inside of the over flow . i cannot keep the water level inside the overflow box to stay at one level , how do i fix this?!

What size diameter is your PVC at the top of the durso?

Take the Dorso up eo 1-1/4 to 1-1/2" diameter and drill a 1/16" hole in the top of the cap.....you won't hear another sound. The diamter you use will be determined by the constraints of the physical size of your overflow.

First try drilling increasing the size of the air hole. You need enough air to get in so that it doesn't "flush". Drill them out a bit and see if it fixes, then drill out a little more, check, etc. My pipe is 1 1/2" and I've got bigger air holes than I'd think. Every so often when they fill up with salt-creep the thing will start flusing on me and it's time to clean them out again.

If you can't get it to quiet down with more air you need to increase the size of you stand pipe & re-tune air mix again. Not sure why exactly, but it's supposed to be bigger than the size of your return.

I just leave mine open instead of capping it, and stick a sponge in it. No more noise
