Kick-Ich or Malachite Green - good for Crypt (w/corals)?

[BigShot]

I have 180 gallon tank... recently, my Blue Tang (Hippo/Regal) got Ich.
The other fish seem to be OK, but a yellow tang already has 2 dots...
I have no other tank to take the fish into... I have live rock, cleaner shrimp, few 'hardy corals, crabs and snails in the tank.
I've used the pepper based meds before (from Kent Marine and some other brand, I can't remember) but they never worked..
Putting copper in the tank is out of the question... cleaner shrimps just don't do it for the tang...
I looked at two products: Kick-Ich and Malachite Green by Aquarium pharmaceuticals.
Both of them say that they aare reef safe.
Two questions (for those who have used them):
- Are they REALLY reef (coral, shrimp, snail, crab, live rock) safe?
- Are they effective?

Huge thanks,
luke

Some have had "good" experiences (i.e. they haven't killed their inverts), and others have had bad experiences (i.e. invert wipeouts). It's all a moot point, as neither one will do a thing for the issue of the ich.
