Thank you for replying. I am very sad and frustrated at the same time. No results after so much money. I have attached a few pics. The carpet looking thing was in the middle of the rock work not on the frag rack. The frag rack shrunk 10% after a week at the very bottom of the tank. The ricordias were about 3x the size as of now. I honestly really want to save the ones on the rack (if all would be great). Pavona is not even 2 weeks old. I do not understand, i checked the parameters they are all in limits. Calcium recently went up a little. I fed the corals yellow sno, I give ocean magik to the copepods this should be pretty close to sea biology on paper. I have also had polyfilter to check anything like copper and stuff and nothing showed up.Its not hard, but something is off...
Sadly, really no way to tell for sure based on description, so maybe few pics?
I doubt that this is strictly light related, probably combination of things.....
