I have a 130 Gal Oceanic tank with two overflows and two returns that give pretty descent flow I am keeping corals and fist. Just purchase a Tunze 6000 with a controller. My question do I need a 2nd or am I ok with the single Tuze 6000 and the controller. The second question the returns are aimed at the front glass should I position the Tunze I just purchased on the side and have it blow across the lenght of the tank?
