This will be my first year to close our pool and to do the winter chemicals. We had a pool guy come out and close it last year and he came back every month or so to add chemicals. I was wondering how that process works. I assume he was trying to keep some chlorine level in the pool. He would open up part of the safety cover and pour in some chlorine granules.
What does everyone else do about winter chemicals? Our pool will be winterized in late October with the pool pump off... Is it safe to pour in chlorine with no circulation? What level should I keep the chlorine at during the winter? CYA level around 40. Does anyone just leave the pool as is until spring, adding no chemicals? Thanks.
