I just realized that I haven't posted a single pic:
Feb. 23 - You can barely tell that the tissue from the tips of this stag are gone
Today (from the other side) -
Feb. 23 - This coral was one of the first to show signs of damage
Today - (it's totally dead)
Feb. 23 - The tips are all burnt, but it's hard to see in this photo
Today - Kind of hard to tell, but probably 1/3 of the tissue, all the way down each branch is gone
Feb. 23 - this used to be my favourite coral. It started with just burnt tips
Today - I don't think there's any saving it. There's no more than a couple cm anywhere on the coral that doesn't have damage
And I don't have any earlier photos of these guys but:
And finally:

You can't really tell form this pic, but the small frag in the dead centre of this pic is a Pink lemonade. It presently has several of those blisters I was mentioning. The freshly de-fleshed white skeleton next to it was a beautiful teal acro with blue tips 3 days ago.
Ugh.
The only glimmer of good news is that since I haven't been able to pick up the big tubs yet (I'm hoping for this weekend), I've been doing at least one 45-50 gallon water change every day since Sunday, and I *think* today I see the first possible signs of improvement. At least I haven't lost an entire colony in a couple of days anyway.
