coral help

I have a frag of what I believe to be a hammer coral (sold to me as frogspawn). The first pic is when I first got it in september. the second pic is from this month. I have it in a 55 gal. Its under 4x 55W PC lighting placed 3/4 of the way up the tank.

last tested params were 12-05-07

ph 8.2
ammonia 0
nitrite 0
nitrate 0
phos. 0
calcium 420
alk 7

I have 41x flow turnover in the tank from 3 seios.





As you can see it has lost its green color. does anybody know why?

thanks

Its 3/4 of the way up the tank.

I have 2 10k and 2 50/50 bulbs. I also have an 18" actinic in side my canopy that I use for dusk and dawn. I have been leaving it on all day because I like the color better with it.

Phosphates tested 0 last time I checked
