Having a swimming pool in almost any region requires some sort of pool heating. Even in the deep south or Florida, if you want to swim all of the year you have to warm the water.
The old method was a blanket which kept the pool from evaporating at night because this process wasted heat from the pools, which were electrically warmed. Next came the solar heating blankets, a pad which, like the original blanket, totally covered the pool surface preventing evaporation. During the day heat from the sun was absorbed into the blanket and this passive solar kept the pool warm at night either replacing the pool heater or supplementing the heat and decreasing energy bills.
The object is to prevent evaporation. This is why a new invention has "surfaced" (literally) in which a layer of lighter-than-water liquid floats on top of the pool water and slows down the evaporation process. The molecules of this liquid rush together when the pool surface is undisturbed forming a barrier to water vapor. It doesn't get it all but just enough to save you money. The non-toxic liquid oozes slowly from a plastic tropical fish-shaped dispenser attached to the bottom of the pool which lasts for up to 1 month. When it is finished it is thrown away and another one takes its place. Each "fish" costs $10.
