I bought 3 pieces of SPS about 4 months ago. Sorry I only know one of them is an acro, but the other 2 I have no idea. Regardless, all 3 were doing well, nice color, starting to branch, good polyp extension etc... I just took the Acro out of the tank and tossed it today, it was completely white, and all the holes where the polyps are located were empty. One of the other corals, is starting to wash out and turn white, but still has good polyp extension.
I noticed the change after I swapped in new bulbs. I have a 6 bulbs T5 setup and changed 2 bulbs every 2 weeks as not to burn the corals. The last set of bulbs was changed 3 weeks ago.
My water parameters are as follows.
Salinity 1.025
PH 7.97
Kh 9.3
Mag 1350
Ammonia 0
Nitrite 0
Nitrate 10
Calcium 325
Phosphate .03
What could be causing this?
