Yes. What are you dosing? It could be your supplements your using. It could be its under different lights. (which is most likely) If you add actinics or 20K bulbs your going to get more vibrant colors............but your going to get more blue hue as well. What lights did it come from and what is it under?

Check your magnesium, Iodine, strontium levels. What's your water look like? Also, what are you feeding your corals?

well levels look great. I would say its just going through puberty. lol. It all honesty its probably the difference in lighting. how high up is it? I think they use 400watt halides.....which is insane. You have to be a coral enthusiest to keep those colors at home. Im using two 150 halides and soon going to add two 36"T5 actinics, so close to 10 watts a gallon of very intense lights. Problem is. my stuff is bleaching, my softies are all bleaching. Moral to the story....its either getting too little or too much. if you can move it higher, do it. :)

Try using some Oyster Feast. I started feeding my corals this stuff a few months ago and all of them colored up nicely and are growing like mad. However, make sure you don't feed them too much because it will shoot your nitrates up.

Your water looks good. The colors could be your lighting. My 10k MH's on my 95 gallon definitely looks different than my 29 gallon with 14k MH's. If you want bright vibrant colors you should go with 14k's or 20k's. The 10k's are more for growing the corals. I'm planning on switching to 20k's in my 95 gallon once the bulbs need to be replaced.
