I have a 90 gallon tank with a corner flow. The tank used to be real loud. Following the advice of this forum I got a i think called a stand alone pipe ( pvc with an elbow thing on top that fits in the over flow intake) and it actually works pretty well. Is there anything else I can do to make it a little less noisy still? I have this tank now in the tv room of my house and my house mates are still a little annoyed with the noise? Thanks
