Here is a 190 Gal. tank and stand I have built. The tank has two 2" drains and a 2" intake for a closed loop with two 1" returns the returns from the sump will be two 1" lines over the top. I'm still deciding on the pumps, but want to run about 1500 gph through the sump, and 1500 gph through the closed loop, any suggestions?
