I am designing 120 DT, a Marine Depot 36 sump, and a 20 gallon display fuge. I think the way to plumb it all is to T off the siphon line and run to display fuge, overflow box there and run to second fuge in sump. I want to use a auto roller mat and get rid of socks. I have no idea what size return pump to use. I will be using two Vortech MP40s and two MP10s in DT. I want to grow Mangroves and possibly clams in display fuge.
