Ever other fish I've bought either came from hobbyists (so were healthy) or just never got ich anyhow. So I never did QT before. I thought, sooner or later my luck will run out, and I couldn't live with myself if I introduced something that would compromise existing livestock. Especially the now 8 year old tang...
So .. I don't know. Maybe the old way I would do it (ie., hope for the best) was still better after all.
Too late now though. I mean .. even if I wanted to raise the salinity now, it would take a week to bring it back up. It remains to be seen whether they'll make it that far.

The nice thing about a quarantine tank is that you don't have to call it quits until you've tried everything. I would medicate immediately if they are that bad and while using copper, start raising the salinity back up.
*edit* I've noticed when treating with cupramine that all visible signs of ich are gone within half an hour and when I treated my achilles for marine velvet, within 10 min he was no longer scratching frantically and his breathing had returned to normal
Another option is a freshwater bath to relieve them of the worst of the parasites.
