You may want to start by reading about Ich identification-Oodinium &
Cryptocaryon. I have had two mayjor outbreaks with ich and found this
the most useful source of information. I printed it all out and put
together a 3 ring binder for reference on this and other things I have
learned about.

There are several types of treatment depending on what type of tank
setup you have.

I would alos suggest a book by Martin Moe. "beginner to breader"

Type in Ich and Search only in rec.aquaria.marine.reefs.

1st be sure this is really what you have before you do any type of
treatments.
