Ich help

[George]

*sigh*
Probably too late for the invertebrates (including corals) in your tank now because one of the ingredients of rid ich is formalin which is pretty deadly to inverts. Do a large water change, as large as possible, even 100%. Run GAC after water change. Don't add any inverts into your tank until you pull all formalin out of your tank.
Move all fish to a quarantine tank to treat ich.
Good luck!
