I have a 568 gph sump for my 55g tank. I also have a hanging overflow box. The splashing and gurgling that I am hearing from my overflow was way too much to handle. You can hear it from outside the room with the door closed. So I bought a ball valve that i hooked up to my return tube and cut the flow in half. It did the job of being much more quiet, but after about two weeks I noticed a lot more crap lying on top of my substrate. I have a powerhead and 3 hermit crabs and snails each, but it still is much dirtier than before I slowed down the flow. I was wondering if there was another solution to decreasing the noise without cutting off the full strength of my pump.
