Ich??

[molybdenumman]

I have finally recovered my reef tank from a long and arduous battle with hair algae. (Alkalinity and Ca way too low) I had to boost my Ca levels with some turbo calcium which finally got her settled down. Since that time, ~1 week ago, my skunk clown, tomato clown, flame angel and bicolour basslet have been displaying what I assume is Ich (white spots all about their bodies). My yellow tang, false perc and banggai show no signs.

How do I go about treating these guys? I don't have access to a quarantine tank.
