What would everyone recommend for a closed loop for a 44 gallon corner tank. I will have a 10 gallon sump with a mag 7 returning water to the tank. Would another mag 7 for a closed loop be good or would it be to much? Also, should I have two outlets or could I work in about three to four? I eventually want to have a mix of all types of corals but if I have to go one way or the other due to size and shape of tank I will probably go lps. All suggestions welcome
