How do you treat ick in a mixed tank?

[mrtgman]

I have several fish and one of my percs appears to have ick. I also have a bt, hairy shrooms, feather duster some polyps and pulsing xenia. Is there any way of treating the tank for ick? I do not have any type of quarintine tank available to seperate him for treatment. Also today is easter and no stores are open. How long can he survive before treatment?
Thanks!

The only real way to get ich completely out of your system is to QT the fish, There are products out their that are reef safe like greenex but they usually don't work. I don't know a whole lot about ich but hopefully this helps good luck
