Hopefully someone will have some insight on this question. I started to close the pool, got it balanced, cleaned, and put in the winter chemicals to cycle a few hours. Pulled the rails and was about to start draining the level below the skimmer then it started to rain and I called it a day. Today it's pouring again so my question is with the winterizing chemicals. I have the filter running, does it matter or should I shut it down till next weekend when I can get back to closing or will have to use more?
