I've got Ich

Last night I encountered my first bout with ich. It killed all three of my new blue-reef chromis before I even knew it was there. My midnight pigmy angel is showing it while my tribal blenny may have it; can't tell because he has facial art.

I don't have the means for a quarantine tank right now. My only option is to clean the tank. What I can do is to remove all of my corals - I only have one decent one and a few frags.

I can place these in a 5 gl bucket with a filter, but I don't know how long the treatment regimine is. If it's overnight then I'm sure they'll be fine. If it's a couple of weeks then we could be looking at trouble.

Ideas?

Edit: I should point out that all of the fish currently with Ich or dead or suspected are new fish. I am in the process now of a 30% water change and plan on heading out to the store shortly.

Has anyone had any luck with any of those treatments that are "reef safe"?

I lost four fish over this. They were all new, and I think it is more my fault than anything else. I should have done a partial water change more recently, but neglected to. All of the fish I had previous to this are fine. If there was a problem with the water it happened over time and they probably adjusted to it whereas the new fish couldn't take the conditions. Interestingly, the chemistry was good. No nitrites, ammonia, and only traces of nitrates.

The only other new fish that I bought along with the dead ones seems to be ok. He's a tribal blenny and has spots as part of his coloration, so it's hard to tell. He's been kind of lethargic, but today he was eating which is a good sign.
