Ready to swim, but your pool still isn’t warm enough? Try a creative solution. Liquid solar blankets are a fun and functional alternative to traditional heating methods. They work by slowly admitting a liquid that traps heat and reduces evaporation. The best part? The liquid is non-toxic and invisible. It does not affect skin, clothes, or pool chemical balance. You won’t even notice that its there. Unlike a traditional solar blanket, it is in use WHILE you are using your pool. 100% safe and works 100% of the time? Can’t beat that!
