Should the solar cover be removed on sunny days?

Answer 1

Sunny days provide the most solar heat to warm the water. So, no, do not remove the solar cover unless you're going to use the pool. And then put it back on when you're done swimming to help keep the heat that was absorbed during the day from being transferred into the cool air during the night. Hope this helps ... On a sunny calm (not windy) and warm day, you will gain more heat with the solar blanket off than on (since the blanket actually blocks some of the sun). On a windy, cloudy, or cold day, evaporation cooling may be greater than the sun warming effect so leaving the blanket on makes sense. Leaving it on day or night also makes sense if conserving water or chemicals is your main goal (reduced evaporation). Leaving it on at night or when the temperature of the water exceeds that of the air by some amount also makes sense. Leaving it off day and night early in the season when the water is colder than the air also makes sense (it will hold the cold in). Leaving it on too long (day or night) makes your pool green.
