not sure what to make of this, but, what started as brown diatoms is turning into an oragne crust on sand and the tops of rocks. it is worst where the light hits the strongest, and none where the light is minimal. i have an truaqua sky led about 8" above the glass top, and run it white, blue, and red from 11am til 9:30pm. then i turn off the whites and leave the red and blue run for another hour and a half. too much light?

Sounds like cyano on your sand bed, suck it off. Reduce light hours and amount of food and that should cure it but hard to say without pictures.
