So, I'm in the process of setting up an SCA 150 with a 16" synergy overflow box, and I've chosen every piece of equipment necessary other than the return pump. The tank is drilled with (2) 3/4" returns, does this mean I should only use a pump with a 3/4" output, or is it really not that much loss from a pump with a 1" output on 3/4" pipe? It seems I'm pretty limited on 3/4" output returns, as I have heard too many bad things about the vectras to spend over $300 on one. Anyone have any suggestions on a reliable, quiet return capable of 1000-1500 gph after 5 ft of head loss and a split for the returns on 3/4" PVC? I'm sparing no expenses on this tank so let's hear it. (Ok other than an RD3...)
