Alright I have 2 tanks with aquatech 30-60 and both of them make stupid amounts of noise. I can't take it any more so I'm going to buy new filters. I already cut the filters short to he'll but it doesn't. I cleaned them put 3 times today and there still anoyying as hell. It may be that the filters in general suck. Anyway. What is everyone's opinions on this. I'd like a canister but I know how they work just not in the tank. And I don't know if its okay with sand.
