Just run it like a normal tank and watch the quarantined fish carefully for any signs of illness or disease.
If your fish does have an illness then raise the temperature to at least 84 degrees F and pour salt in it. Keep up with the process till your fish is fully recovered.
Oops Edit!: Also before you put salt in you should do at least a 65% water change and do one about every 3 days. Everyday if your doing 15%.
