So that leaves me...

I don't think I've got any problems with color. But with the one 400, I place the coral directly beneath it that require it. Just the other day I moved a Monti,or something, that had gotten very light. At first I thought it had bleached out but I could still see very pale blue mouths.

Some of the coral in the middle can't seem to get enough light.

But then again, I'm a bit of a noob. What I may be seeing may very well be the result of too much light.
