Based on what I've read I thought I was supposed to drain the pool to 4" - 5" below the skimmer and then winterize (add chemicals). I just received my winterizing kit and it tells me I should add the chemicals while "circulating pool water". Am I supposed to close the skimmer valves and leave the main drain valve open and run the equipment or just add the chemicals before I drain the pool?
