As the water temps drop and the SWG stops producing chlorine, we will obviously be using bleach for the winter. Pool will be left uncovered. With the recommended levels of CYA differing for SWG and Bleach methods, do we need drain pool to lower CYA? SWG recs 60 - 80 for SWG and Bleach is 30 - 50.
Water Temp around 55
