I'm looking to get a new return pump for my 65g tank. Currently I'm running a Waveline DC4000. It's rated at 1050gph. I have 5ft of vertical line and 1 ft of horizontal. I will also be feeding a gfo reactor and a chiller which requires 600gph pass through. I'd like to have 600gph through the sump as well. With 1300gph required flow and the head loss, would the M1 be enough or should I get the l1?
