If you do not have prepared saltwater use the tank water.
Make sure the water is the same in the QT as the tank. salinity, Ph and temperature.
Purchase a product call Mardel Maroxy for Saltwater. Phone the lfs first before you go.
Follow the directions to a tee and do not use carbon in the QT

Without observing the fish it is possible that the fish had ich at some stage before you bought it, was treated leaving tiny 'sores' where the ich was once attached. The damaged skin attracted a fungal bacteria which is what you see.

Obsere the fish to see if the the cotton is gone is one or two days.

Continue feeding your fish garlic extreme soaked dry foods, feed only garlic soaked foods and overfeed including the fish in the QT
Good Luck
