Hello all..been out of the hobby for a few years..Back in with a 120g setup with sump...just powered her up this even and it is LOUD..lots of splashing and water noise. I think the main culprit is here, the input from the tank. It has a filter sock over it, but it just overflows the sock and still makes noise. This is my first experience with a sump so any advice would be much appreciated. I apologize in advance if this is in the wrong subforum.
