overflow and return ?


New member
What I got so far is 120gal DT and a 55 gal sump. goes like this. skimmer/return/refugium.wanting about 75 percent to skimmer section and remainder going to fuge then return. ill have a CPR Continuous Siphon Overflow at 600gph and a Supreme Classic Mag Drive Pump at may 700gph. I will do my best to not use any 90 degree angles in my PVC. So my question is what should I think of or what have I not thought of? Still a couple of weeks before I do this. But I just wondering. Thank
