Didn't have much time to post yesterday but here's the way things stand. As mentioned, two frogspawns are gone, as with the orange crush, another aussie acan, and half of my elegance coral didn't make it. My other two aussie acans are on the mend and looking EONS better today. Pretty much everything else is happy but I'm worried about my Orange Torch and Bubble. Both had significant recession of flesh and are no longer extending flesh over the edges of their skeletons. IME this usually leads to continued slow recession and death of the coral over the course of weeks/months, but we'll see. I'm gonna have to really stay on top of the chemistry and skimming in the next few months and see if I can't coax some health/growth out of them.
Still hurt to loose the 4.5 colonies that I did (specially since they were some of my favorites) but at least I caught it before the problem got worse. AC will not be off again for the rest of the summer so this problem won't rear its ugly head again.
