Given time, in a tank without a host the parasite will die.
QTing is the best measure to prevent and why you should always QT. I QT'd even my Achilles tang and he made it through, even given the fact he was on his way to death at the store.
If you don't QT you can introduce a fish with ich that is not showing signs of it.
The time spent QTing is nothing compared to the time spent dealing with a parasite/disease once it enters the system.
