What has occasionally worked for me is to just siphon off the infected area at least twice a day until the recession stops. However if you're not going to be able to access the coral until the next time you're home there may not be anything left.

Dangit, too late to go get the saw from Princess Auto. The few days after Christmas Canadian Tire had their $149.99 Craftsman wet tile saw on sale for $45.99, but I talked myself out of buying it. I didn't even have corals on my mind otherwise I would have talked myself into buying it!

Ya, I'm not going to be around to siphon off the coral otherwise that's what I was wanting to try doing. Thankfully this disease is slow moving. It only moved about 1/4" in two weeks. I first noticed it in the first week of December I think it was, and in that whole time it hasn't even reached an inch of recession.

Anyway, I decided to take my rotary tool to the coral with a diamond wheel on it. It cut easier than I expected, and I used a chisel to pop each cut section off. I took off the dead tissue plus about 3/8" of healthy tissue. I hope that's enough. I noticed green on the skeleton where I cut, and I worry that the problem is actually a parasitic algae (other than dinos, which aren't alga anyway). Hopefully when I come back again in two weeks I will see healthy tissue on the cut edges.

Sorry Favia, I wish I didn't have to do it to you...
