    So I just added a sump to my 80 gallon predrilled tank and I can not get the sump to flow to work right. It either wants to over flow the tank or run out of water in the return pump.

    Make sure your overflow GPH is greater than your return pump GPH. Ex: get an overflow that is 500 GPH and a return pump 450 GPH
