I'm thinking of replacing my current lighting over my small frag tank. The tank is a 25 gallon Innovative Marine Lagoon (24X20X12.) I'm going with a 24" 4 bulb ATI. So there's two questions I need help with. 1) Do I care if it's dimmable? 2) I am considering attaching two Reefbright XHO strips as well. Too much? Overkill?
