Sandy this thread was not meant to imply that all or even most tanks are immune from ich. All tanks can be infected with ich especially new ones which will almost definately become infected if you don't quarantine. For some reason, in some tanks, the fish may become partially immune but not all tanks and certainly not in new tanks.
You should take out all the fish to treat and leave the tank with no fish for 6 weeks. You can try to leave the fish in there and hope they will get cured but I think you may lose all of your fish.
Sorry.
