5 Reasons a Solid Pool Cover Beats Every Other Evaporation Fix

A solid cover cuts evaporation by 90% or more Water evaporates into moving air, not still air. A cover blocks wind and sun from the surface, stopping most water loss.

Liquid covers are a poor substitute Monomolecular layers break up from wind and swimmers, need constant reapplication, and don’t work at night. They help a little but are no match for a real cover.

You lose about a quarter-inch of water daily without a cover In hot, dry weather, that adds up fast. A cover is cheap compared to the water bill.

Solid covers also keep debris out and can heat the water Solar covers warm the pool while blocking evaporation. You get two benefits from one purchase.

Wind breaks and shade only help marginally Fences, hedges, trees, or shade sails reduce evaporation a bit, but you still lose water. A cover is the only real solution.
