Hi kerusso316,
If your guy is recovering from Velet, a dinoflagellate that infects the gills and skin, the best course of action IMO is copper.
Fresh water dips are effective in killing the free swimming dinos but not encysted stages.
Are you positive that you have Velvet?
Or maybe is it that you have Lymphocyctis? A virus that appears as white tufts?
A picture would be appropiate for better identification
