Previously I had a FOWLR tank and a reef tank, that ran independently of each other. They both had their own fleece rollers (Bubble Magus, medium size). Recently I combined the systems to a 75g sump and added a frag tank. Its too much flow for all 3 tanks to go into one of those filter rollers. Right now both fleece rollers are in the sump, the reef and the frag tank flow through one and the FOWLR flows through the other. Would it be possible to manifold the drains and feed both rollers together? I was going to try it the other day but I dont want to replumb the PVC only to find out it wont work. Any opinions or Ideas would be appreciated.
