This is a weird one for me. I have a 72g bowfront with many corals- 2 montis, a birdsnest, a few softies, and several LPS. I have all of these under T5's. Everything has been great and thriving for many many months. All of a sudden, my SPS started turning white, quickly. My birdsnest turned in a day. The others are starting to turn to. Before you say you can't grow SPS under T5's, my ATI bulbs were working and everything was growing like crazy. I think this happened because my giant mushroom coral closed for a period and secreted a slime/new top. Could this be the cause, and if yes, can this be reversed. My water quality is good: other than alk, which I am trying to raise. The tank has been up for 2 years. What do you think?
