How many days in a row should you leave solar cover on pool?
It depends on several factors. During the swimming season, I keep my cover on until the pool starts getting hotter than I like (over 90). I believe the instructions for the covers say to take them off if the water is hotter than 90. Once it cools off enough, I’ll put it back on. It’s frequently on for weeks at a time, coming off only for an hour or two of swimming and then back on. Another reason to take it off is to allow the sun to kill algae. If you find you’re getting a lot of it, leave the cover off for a day or two.
