Tank Cover

[mnoll406]

Hey Tony,
I wouldn't call it bleaching, the colors have just faded. A prime example is a frag of that purple Acro I got from you. When I got it the tips were purple, and the lower branch was green. Now the whole thing is a light green. I also have another acro that I have had for a long time that started out a light green, and is now a whitish green. I also got a frag from Evan at the last frag swap that was a maroon/purple color, it is now a light purple with intensely purple tips. Just trying to figure out if my tank was getting too much UV or not enough. Most of the corals have great color, just those 3.
