I will soon be posting up my thoughts on the DCs. I have 4 DCT15000's. 2 for closed loop, 2 for returns. I am curious though how they will do with my returns. I have it going 1 1/2 out reduced to a 1" header and then to 3/4" line locs. Each return pump will feed 4 separate return line. See pic, not the best pic but it will help you get an idea. There is probably 4ft of line coming from the sump to the top of the tank where it splits off. I am hoping it doesn't lose to much flow.
