Description: [Keep swimming pool water unblocked and save water] You don’t need to add water even after a few days in the last swim, because we can reduce water evaporation by 95%. You can reuse the water because our swimming pool cover keeps the swimming pool water flowing. Help your swimming pool clean and leave when not in use. [Clean pool water] The pool cover uses the power of sunlight to heat the water, so you can swim by heating the water in advance or keep the water temperature after swimming. And continue to swim throughout the season. [Thickness] Our swimming pool covers can heat water faster, higher and more durable. [Perfect choice for above-ground or underground round pools] Very suitable for simple suits with feet and metal frame round pools! Insulation covers for underground and above-ground swimming pools. [Durable and safe] Our swimming pool cover is waterproof and will not be damaged by immersion in water or sunlight. You can continue to use it next summer.
