Just wondering, how much and how important is it to keep your level of chlorine up in the winter months? Our weather here in eastern NC runs anywhere from 19F at night to 60F days or some days it stays in the low 30's but not more than a couple days to a week. The pool water temp is about 50 to 55F on average. I have been running the pump at night and off during the day. This is an IG 24k gallon pool vinyl liner with DE filter.
I have been stocking up on the bleach for this coming season. The Family Dollar has the 182oz, 6% bottle for $2.
