Grab some of that Gladwrap plastic wrap that seals itself; you can use it to cover the rubbermaid container without losing any light *grin* I forget the exact name of it, but its a little stickyish on one side (theres a commercial for it with the Mario guy from The Food Channel running on TV nowadays).
It can take a little while for the parasites on the fish to disappear. As long as you've seen a noticeable reduction in 5 days things are on the right track
And yep; no new fishies in the tank till ich is gone. You can get new fish tho; figure at least 2 weeks of QT
(if not more). By the time QT
is done, the tank should be ich free. And there is nothing wrong with a longer QT
period if you have to wait a little longer to rid the tank of the pesky buggers.
