too much light??

[martym]

Just wondering if I have too much light in my tank. Tank is 50g with the Teck T5 6 bulb light. 4 bulbs are the giesemann aquablue + and 4 are giesemann actinic. The reason I ask is that I has to monti caps, on is in a shaded area and it is a deep orange color the other is in full light and it is a pale brown , almost see through. Both are from the same original coral. There is also a digiata that was nice and brown, it is now almost white but still has full extention at night.
Should I change a couple of the aqua blue for some 6500k bulbs?
My other coral, some blue, green, and purple, are doing fine.
