You don't want to use PIF to raise the potassium level, but you can use it to maintain it. When used properly that is exactly what it's made for, maintaining both potassium and iodide levels. By "properly" I mean never exceeding dosing instructions and using a little common sense. For example if it states 1 drop per 25gal daily I would assume this is for a fully stocked high demand system, if you have a medium demand system you would dose half.
