Currently running a 4 bulb 24" ATI Powermodule over a 40 gallon tank. I'm contemplating on switching over to Aquatic Life T5 fixture with two XR15 G5s. Tank is mostly acroporas, so I am hoping to get more PAR near the two ends of the tank and a bit more pop from the acros. The ATI powermodule does have strip of LED in the middle but I turned it way down since it creates a hotspot directly below it. I just wanted to hear from folks who had made the switch and what their thoughts/experiences were. Thanks.
