Hello! I bought a 120 gal off Craig's list with a 55 gal sump. I can't get my intake to balance with the return. The intake has an adjustable valve, and the return pump is run through a light dimmer. Still, I have been tinkering with it for days. The water is always raising or lowering. I can't get it balanced. Please help!
