I have a BTA and maxi-mini under LEDs. Both are in a 10, under a 12 diode LED kit from Rapid LED. All 3w LEDs, 6 cool white, 6 royal blue. Both are doing very well at the 3 month mark. Definitely not suffering from lack of light, that's for sure.
Please forgive the BlackBerry quality pics. This tank is in my office, and that's all I have handy.
