We have a 2 year old 24,000 gallon IG SWG pool with a cover in southern California. It rarely gets below freezing here.
My pool has been pretty much maintenance free. I add 1/2 gallon of muriatic acid twice a week to fight PH climb but that's about it for maintenance.
Last winter I covered it and ran the pump on a reduced schedule (every few days I would run it for a few hours) while still adding acid occasionally.

Can I leave it covered and stop running the pump completely? Do I need to worry about the PH rise? Will it even rise without the pump? Can I just dump a bunch of chlorine into it and stop pumping for the next 4 months?

Most of the pool closure threads here deal with colder regions so I haven’t found much on climates like mine.

Thanks
