Forget the watts per gallon thing. Too many variables. If you ran say 4 54 watt T5's you have 216 watts. However your critters are more interested in PAR. A 216 watt T5 system with 2 actinic and 2 ATI suns would have a lot less PAR than one with 2 aquablues and 2 bluepluses. You also have to consider the reflectors and how tall the tank is.
