loss of green pigments in certain corals in the tank

[kwirky]

I'm trying to figure out why my favia frags lost their green pigments, and my euphyllia has lost a lot of it's green too. My red echinophylia is fine, and the green/red zoos are doing great for colour too.

The favia's growing, but the echinophyllia isn't, really. I did have a calcium imballance (low calcium) for about a month. ran the system at 320ppm waiting for calcium chloride to come in from littlesilvermax. Maybe I should give it more time, now that my calcium's back to normal?

Oh, I have a t5 teklight 8 bulb system. it's 50% aquablue and 50% aquablue+. no pure actinics.

my bulbs are due to be changed this march, and I'm thinking of switching to 50% actinic, 25% aquablue, and 25% aquablue+. saw the colour combination at Gold's and liked the look of their BTA's.
