My tank has two 2" overflows with two 1" return pipes from the sump. What size pump is good for this situation? The display tank is 300 gallons and the sump is 75 gallons.
Mag pumps can be external or internal. Both the input and output are threaded for hose barbs. They are my choice for there quietness, size and reliability. Good luck!
