Zoo's Problem Help Please!.

[Robert_Mid]

Hey to all how are you here i'm again with this problem. Since almost 1 moth ago i have to my Zoo's colonies not expanding and almost or always all are closed. To the begin i tought in my light too strong for them so i took them and put over the sand. Then they won't open the same thing so wich could be the problem?.

I'm thinking in use Carbon Activaded or something like that cause they are the only corals sick's cause i have a Purple Linckia Sea Star and it's fine. The rest of the corals are doing great with no problems but my Zoo's are looking really bad.

I have a Current USA Satellite Fixture 4X65W PC's, and my tank it's from 36G + 25G Sump/Refuge.

Here are the pic's.
