man, so sorry! I hope things bounce back. I'd just remove anything dead and go with the aforementioned advice. Water change, carbon and wait.
I had a BAO TSA Transport leak on my way home from Fox's place this weekend (it had about an inch left in the bottom when I found it and then scavenged water from the other two containers in an attempt to mitigate the damage) I estimate the frags in that container were basically out of the water for 2 hours and everything lived. Corals can be more resilient than you think. Good luck and keep us posted.
