Don't use meds and salt, at least make sure its ok. Most of the time when using meds they will recommend just meds.Personally I ld stay away from meds. They can he harsh and stain your silicon, decor etc.
If you did the heat/salt method. You would treat for 10-14 days.
Slowly raise temp to 86 degrees
1 tablespoon of Kosher salt per 5 gallons dissolved in a cup of tank water everyday.
With the temp so high your going to have to lower your water level so the filters are really agitating the surface to help oxygenate the water. You also add an air stone.
Every 2nd day do a 50% water change and give your substrate and decor a really good cleaning.
After the 14th day if you don't see any signs of "white spots" ich treat for 2-3 more days.
