Min 3 wks from the time that you last saw the ich visible on the fish.
I agree about the UV although many make compelling arguements that it does not work. Ultimately it is not going to cure an outbreak of ich, in my opinion. If a few parasites makes its way into a UV sterilized display, it will likely handle them.
My point is just that why go thru all this when you can QT? A UV is not going to touch most fish diseases, even if you do feel like they are effective with ich.
Anyway.....just for discusssion sake.
