My pool will be unattended for 19 days in September. I live in Central Illinois.
What should I do with the pool while I’m gone?
1. Should I bring it up to shock level the day before I leave and let the circulation system run as usual? It is on a timer. It would run about 7 hours per day. I have an opaque, automatic cover. So I would probably lose at most 1 ppm of chlorine per day.
2. Should I bring it up to shock level the day before I leave, then shut off the circulation system and let it sit for 19 days? If so, should I drain and clean my DE filter after I shut the circulation system off? Again, the opaque, automatic cover would ensure that I lose at most 1 ppm per day.
3. Other suggestions?
After I return I would get everything up to snuff and then close the pool down for the season.
