I have a 125 FOWLR
but have an anenome, 2 clowns, 1 CBS Shrimp, 2 cleaners, 1 damsel, 1 regal tang. I have had the same setup for over a year and a half. My question is I have a mag 12 as a return from the sump into the tank. For circulation, I have 2 Via aqua 480's, a Via Aqua 1300 and a med size Via Aqua (dont know what size) all inside the main tank...they are mounted on the far left wall of the aquarium where the predrilled portion of the tank is. In other words they are all on one side of the tank....2 of them are blowing left to right and the other 2 are facing the front part of the tank....combined with the return, it creates a round the tank circulation in a big circle. i dont like the looks of the Via aquas any more so what do you guys recommend as far as placement (in my case) and how many powerheads do I need for a 125? i think I might have to many?? All of the pumps just seem to clutter up the tank.
