I recently built a frag tank for my SPS which have been growing under t5's for years. I bought two radion blues. My frag tank is 12 in deep and the lights are mounted on the arms . Although my colors are good I always thought they would be better under higher par and I always wanted to try out LEDs. I am currently running the ab program at 60%. My question is what are your thoughts as to whether or not 60% on a 12-in deep tank is too much
