HTH™ Pool Care Liquid Solar Blanket forms an invisible barrier on the water surface that reduces evaporation by up to 40%. This helps retain heat and can reduce water, chemical, and energy costs without the hassle of a physical cover.

HTH™ Pool Care Liquid Solar Blanket forms an invisible barrier on the pool water surface that slows the rate at which water molecules escape into the air. This can reduce evaporation by up to 40%, so you refill less often, lose fewer chemicals, and retain more heat.

Shake well, then add the label-directed dose to the pool water surface opposite the skimmer while the pump is running. Reapply weekly for best results. Wait 15 minutes after application before swimming. When used as directed, the product will not affect water chemistry.

A liquid solar blanket is not as effective as a physical cover for heat retention in very cold weather, but it is more convenient and still provides meaningful evaporation reduction throughout the swim season. It is ideal for pool owners who find physical covers difficult to manage or want continuous protection without covering and uncovering the pool daily.

No. When used as directed, HTH™ Pool Care Liquid Solar Blanket will not affect pH, chlorine, alkalinity, or other water chemistry parameters. Its nontoxic formula disperses quickly and does not affect water feel, clarity, taste, or odor. Wait 15 minutes after application before swimming.

By reducing evaporation by up to 40%, a liquid solar blanket can meaningfully reduce water, chemical, and heating costs throughout the swim season. Every gallon that evaporates carries heat and dissolved chemicals with it, so less evaporation means less refilling, fewer chemical top-ups, and lower heating costs, particularly for heated pools.
