These LED's just aren't cutting it. Or - are they?

I find the white spectrum is more responsible for high light bleaching but generally you would reduce the entire spectrum to acclimatize the corals to the new light. Most people experience coral bleaching when they make the switch due to running the fixture too high, the visible light is much different.
