I just want to make sure I am closing my pool right. I am thinking of doing a partial closing, if that's a thing. My area does get to freezing sometimes, but not for extended periods. Snow is rare, our rainy season is in the summer. Can I get my pool to ideal levels after shocking, but not drain the water below the skimmer and put my safety cover on? Basically it would be "open" chemically and water level wise but closed because of the pool cover. I normally run my pump 24 hours a day. For nights when it is colder should I increase the speed? My usual night speed is about 1300 rpms. Can I just have the pump only run at night, or should I continue to run it 24 hours over the winter?
