PRO SERIES® Liquid Cover

Liquid Solar Blanket

Problem: Swimming pools lose energy in a variety of ways, but evaporation is by far the largest source of energy loss. Evaporating water requires a tremendous amount of energy. It only takes 1 BTU (British Thermal Unit) to raise 1lb of water 1°F, but each pound of 80°F water that evaporates takes a whopping 1,048 BTU of heat out of the pool.*

(1 gallon = 8.33 pounds). Therefore, for every gallon of 80°F pool water that is lost due to evaporation we lose 8,729 BTU of energy.

Solution: PRO SERIES Liquid Cover’s advanced mono-layer technology offers users the ability to save water and money by dramatically decreasing evaporation and heat loss.

  • Liquid solar blanket
  • Forms invisible one molecule thick mom-layer on pool surface
  • Reduces evaporation and heat loss in pools
  • Reduces frequency of water adjustments due to reductions in water loss


Directions for use:

Weekly add 4 oz. per 675 sq. ft. of surface area, assuming an average pool depth of 4 feet (20,000 gallons) or more.

For gutter system pools or pools with high splash out or drag out: dose 2 times per week.

Important: Circulation system must be running during application.
