I always read the blue gives the color. Example: the 20k halides are known to produce deep color?

Hmmmmm
It has been proven the excess light in the 685 nm range will cause clor bleachiung in many corals. This is at the high end of the RED part of the spectrum. So the question is what is your White to Blue ratio? And also what type of White LED's are you using? I perfer Neutral Whites as they give a strong spectrum of red at about 630nm but fall of to near nothing by 685 nm.

Then there is the possibility of the light being overall too intense as some have said before. But this is very less likely.
