NOS-ICH anyone tried?

Most people keep the DT fallow for 8 weeks. Most strains of ick will be dead then. Any less, then you are gambling.
I would QT the mandarin as well. Ick also infects fishes gills where we do not see the parasites.
I don't do hypo, but I thought the lowest you could go was 1.009?
I do tank transfer. Once your DT is free of ick, you might consider this method for your incoming, usually one fish at a time.
