I've beaten Ich before without transferring fish. My fish are pretty big so putting everyone in another tank wasn't an option. I used garlic on food and used voogle which is an immune booster.

You can't remove it totally from the system with fish still in there. It will definitely still be in your system just the fish now have a level of immunity to it but if one fish gets ill or stressed enough you could well find it rears it's head up again.
I know of another reefer who had not added a single thing to his system in 4 years and all of sudden WS appeard .
I personally think it's in all systems just waiting for a victim no different to the Flu amongst humans the older and weaker you get the more likely you are to get it.
