This is my first sump. I've only use canister , hang on the back, and biocube overflow. There are 2 sections separated by baffles in my sump. The main section with my live rock and cheto and skimmer is just so still and looks motionless. I know there is flow because it's returning to my tank through the pump. I'm just asking if I need a small circulation fan to get surface breakage? ?... or do I let it be just as is?
