Hmm, I guess the kits I looked at were meant for reef tanks then. Good to know.
So samamorgan, with your suggestion, I'd have the two center blue LEDs on all the time and the cool whites on just for a few hours per day?
Wingo, I think I'll PM you about drivers once I've finalized what I want to do with the lighting.
Also, since I won't be running these at full power, what do people suggest? 1/3 of the full power? Obviously I want to grow plants and not algae...
