White fuzzy growth on coral

[SteveConn]

Well, I fragged off the affected parts of the coral. There is still a small spot left. I want to get my microscope out of storage (moving soon) and take a look to get a better idea of what I am dealing with. Anyone interested in pics if I do?
I'm a little surprised that nobody else has had this issue... lucky me! This stuff took about 1/3 of a caroliniana colony.
