I am setting up my new 40 Gal. tank and was wondering, were or how is the best placement of my return from my sump. This tank will have assorted corals and some softies. Should I run pvc from the pump and have it pump to several diffrent areas and levels of the water column. Or should I just use the piece it came with that just hangs over the top and spits out in the one spot up high? Could I pump the water from the sump to enough diffrent spots to reduce the usage of power heads? The tank is a corner tank, I have a mag drive 5 pump 500gph. Any input on this is appreciated.
