Well, backstab, I hope it works out, but to be honest with you, from your description of how you handled it, I would not be suprised if you saw ich rear up several days down the road.
Copper treatment requires consistent treatment for 3 wks with viligent attention paid to maintaining theraputic copper level in the tank. [Meaning you need to test copper levels daily].
If you read the post on ich in the FAQ Thread, you will see why you don't see ich at the momement, and why you may well be seeing it again in the near future.
