What size return pump should I use for 60 gallon cube with standard corner overflow. I plan to place a 3 valve manifold; one for calcium reactor, one for phosphate reactor, and one that feeds back to fuge. All running off return pimp.
That's a lot i'd use a mag 12 at a min. but would lean toward the 18 if it were me.
