CoryDude, I had the same issues with SPS are you are, they all lost color after I switched from my MH/VHO setup to my AI Vegas. What I recently figured out is that they were getting TOO much light, specifically the white LED's. I recently turned the whites down quite a bit and all of my SPS are slowly regaining their color. My orange montipora was almost all white, it's now turning orange again. My pink birdsnest was also almost all white, but now is a nice pale pink. Same story with others in the tank. I couldn't keep any acans in the tank, they would just shrivel away. I now have a colony that I got from Allan and it's doing great.

I think part of the problem for me is I have a 36" long x 18" deep x 19" tall tank, and I have two Vegas since I figured I needed to for coverage, but this is a TON of light for my 50 gallon tank.
