Here is a good article for ya bud The Coral Whisperer: Bleaching and Tissue Loss in Corals - What's the Difference? — Advanced Aquarist | Aquarist Magazine and Blog It will give you lots of factors that can cause bleaching events. I have far more experience with halides and the par they produce than t5s and what they are capable of. I hope you get it figured out bud.

I tend to think like many others. Colors are reflected to our eyes by pigments in zoanthellae in coral. Pigments absorb light. Too much light makes corals expel zoanthellae to reduce light energy being absorbed by their tissue, resulting in the appearance of less color.

That being said that article has broadening my mind a bit on the subject....thanks.
