Oh, Hey! The folks on Elbow Key! Yeah, the solar cover should be ALL you need there. Use the cover when you are not swimming and:
1) on sunny days it acts as a greenhouse to heat the water
2) on cloudy, rainy days and at night, it acts as an insulator.
3) keeps stuff from getting in the pool
4) inhibits water evaporation, reduces chlorine loss.
5) inhibits pH rising by reducing natural aeration
