So Im wondering how to size a return pipe for the tank im building.
72x20x20 central overflow (2x 1.5" holes for drain/emergency) and 2x 3/4" return lines
the sump is 5ft long and 16" high
the stand is about 32" high so pumping from floor to top of tank is no more than 52" (4.3 ft)
Im wondering if I could get away with a Mag 9.5 for the return which at 5' is rated for 750GPH or should I go with something a bit bigger which throws out 1000+
Only reason I am bringing up the Mag 9.5 is because I have found a wicked good deal on them at a LFS
