been doing 50% daily.. and kept the temp up to 85 range. have not added salt at the moment. and have not seen any sign of the ick. plan on maintaining this for the next 4 weeks. If the Ick does return then I'll start adding salt. BUt he's doing very well, eating like a champ, and no sign of gill problems. I believe it caught it very early. Thank you for the imput.
