Thought i'd update this. The slimer continues to STN. Each day a little more. So Monday i fragged 4 braches off it and put the rest of the coral in a tupperware container overnight with 3 drops of Lugols to about 2 cups of water. Woke up next morning expecting it to be completely white. It wasn't, so i put it back in the tank. The frags looked good the first day, all of them had decent PE. But as the week has gone on, the frags are losing more and more color and PE is declining. The main colony has not shown any PE all week, it has browned out, but the STN has stopped. This afternoon the frags look terrible, so what the heck, i tossed them in the container with 3 drops Lugols until i get home from work around 6. We'll see how it goes from here.
So i think i will lose the slimer completely. The purple acro has not worsened. But it has not grown any new flesh over the bleached area either.
I just can't believe i'm going to lose the slimer from having it in a lower flow area for 4 days. Reminds you how delicate these corals are.
