Solar Pool Heat

I do have the debris cover and was wondering if these "solar covers" really make a big difference.Are the debris covers designed to heat the water? I have a neck injury and the gravity freedom of water is SO helpful but the temperature of the water is almost counterproductive for results. Help me finf a way to get a little warmth.

Depends on the color and the composition of your debris cover. It the debris cover is a dark color and not layered to at to provide some sort of insulation, like trapped air in a Quilt arrangement, then a solar cover will offer you little or no difference.
