Did you know that normal evaporation could cause loss of water that may require filling the pool?
While evaporation occurs in every body of water, the rate of evaporation is determined by a set of variable factors including : air temperature, level of humidity, water temperature and wind velocity. Most of the variables change as the seasons change or as the sun rises and sets. The industry is taking steps to educate pool-owners to reduce evaporation loss through the use of solid or solar pool covers
when pools are not in use. This effort could reduce total evaporation rates by almost 50% since the pools would be covered at the times when the evaporation rate is the highest.
