I'm building a sump for my new 54 corner bow front.I'm putting a closed loop on it also.My sump will be 14-15 gallons at operating compacity.I.m trying to keep my return pump dry.What size return pump to use.It used to run off a mag 9.5.But that ran the skimmer and u.v. also.My skimmer will have its own pump and I won't have a u.v.I would like to use a mag 7 on it.Should that be enough?
