I upgraded to a standard 120 (4'x2'x2'). I currently have two Tunze 6095 (running probably 1/3-1/2 speed max at the moment) on the two back corners blowing not quite diagonally across the tank. I envision having two MP-40s on either side of the tank in the future on both end. Do you think that is too much for the 120 for a sps tank?
