What strategy can be employed to reduce water evaporation from a pool?

Using a pool cover is an effective strategy to reduce water evaporation from a pool. When a pool is left uncovered, water can easily evaporate due to exposure to air and sunlight. A pool cover acts as a barrier, significantly limiting the amount of water that can escape into the atmosphere. Additionally, using a pool cover helps to retain heat, which can contribute to a more comfortable swimming environment while also conserving water.

Other strategies, such as increasing the pool temperature, tend to exacerbate evaporation because warmer water evaporates more quickly. Lowering the water level may not effectively mitigate evaporation and could also lead to other issues, including reduced swimmer safety and water circulation problems. Increasing the usage of pool chemicals does not contribute to reducing evaporation and may instead lead to more frequent adjustments of chemical levels due to potential chemical imbalances.
