I'd not put it in the display quite yet. At least 4 weeks with no signs of ich present.about two and a half weeks.
Thanks, damon.If you're doing 100% water changes frequently and cleaning the buckets so there's no place for the parasites to drop off and incubate in the substate, I'd say you're good.
That's the key to breaking the life cycle...you've got to remove the parasites when they want to incubate.
So, basically, it really depends on your procedures as to the time the fish should stay in the bucket.
