LEDs Causing Algae on Sandbed

[Madreefer]

You should be good with 6. My tanks 57" long, rounds out at the front 29" and is 25" deep. There's SPS, LPS, zoas, a clam anemone and all doing great. You'd be better off supplementing with purple or pink T5s to bring out your reds. I like mine but this algae thing is my only complaint and i'm positive it's due to a setting that I have yet to figure out.
