Also I picked up one more purple stylophora frag from my LFS to "test the waters" last week and so far so good, it seems very happy, actually coloring up in some areas where it probably wasn't getting hit with good light at the store. This is one of the frags I lost to this incident so it should be a good test. Also I have one acropora, a raspberry tabling variety I believe, that has been completely unaffected by this whole thing (the only SPS that came through unscathed) and it's showing signs of growth now so that's a nice consolation.
