When should a solar pool cover come of during the day?
I’m geting conflicting advice on my solar pool cover… It’s opaque blue… My Q: If the air temp is significantly above the water temp, the sun is shining directly on the pool, and there is minimal breeze, will the sun heat the water more effectively with the cover on or off? My liner is a deep blue…

A solar cover is designed to absorb more sunlight and heat into the water. You should put the cover on when the heat of the sun is shining on it, unless your using the pool at that time. It is also a good idea to keep the cover on at night to keep the cold night air from cooling the water.
When your using the pool.
I agree with the dudes above…the cover should come off when using pool…water cools by evaporation!
