OK so not sure where to post this so I'll do it here. I've been having problems with my corals, not sure if it is with the lighting or the water. I first noticed it about two months ago. I transferred over all my corals from my 55 gallon with compact lights to my 150 with medal halides. As soon as that took place all corals opened up but never started growing, they actually got smaller and started dying. Now I have been testing my water like every two days, I found all my levels off--
Calcium - 440
Since I tested that I have done 3 40-Gallon water changes in the past 2 weeks, and now got my levels somewhat normal--
Calcium - 400
I was able to save 3 of the 12 corals I had
and only one is doing better then it was before. One (the brain) has lost is red color and is total white, but really think and pumped up. The other which is like a frog spawn has retracted in and is not coming out, but is not dead yet. I have a clam and it looks as nothing happened in the tank, and all my fish are great. So I'm not sure what is going on and don't want to put anything in till i understand it. I was hoping someone could give me some advice. I'll post some before and after pictures so you can see what is going on.
Please ask anything you need to make a great educated guess to the problem
