Monitporas and LED

[therealkilo]

Lighting:
Photon 48-W's
Tank mount (6" above water give or take).
70% Blue and 47% White using the excel document with a 10 hr lighting period ramping up and down.

I have been slowly ramping up to this over the last 4 months.

Trying to figure out if I should keep ramping up channels but some montipora capricornis plates look really bad. Some are getting white and some look like they are disintegrating.

Tank Specs:
Standard 55 Gal
Height 20"

Some caps are sitting on the top of a LR wall and are around 12" from bottom of tank or 8" from water line.

Thoughts?

Bleaching can certainly be a sign of too much light, but there are a lot of other chemical imbalances that will do the same thing. What are your water parameters (calcium, alkalinity, magnesium, salinity)? How stable are those numbers? How often are you dosing?
