Okay LPS people, I need a little help here. I bought a galaxea coral that looked fine in the display tank at the store. When I got home I realized that it had a bad spot on the back with a white slimey looking substance on it. I dipped it in Lugol's Solution and scrubbed the white filmy stuff off with a small brush and now it is in the QT. I know that on flower pots if you get a bad spot the coral is pretty much doomed. Does it work the same way with this coral, or can it be saved? It opened and looks great except for the little brown bare spot on the back. Is this something that could spread to the other corals in my main tank? Do you think it's just coincidence that any bad spot on a piece of coral is ALWAYS facing the back of the tank???
