Just about to build a sump for my 75 gallon. I’ve been browsing around all afternoon to acquire a sump, I found one. Now I gotta find a return filter, my LfS’s don’t have any in the shelf anywhere. So I’ve been on Amazon… with that said what are some pumps that everyone likes. I’ve been looking at the jebao doc series and thought about grabbing the 3500. What you guys suggest on GPh for a set up my size. Thanks in advance
