What can be used to reduce water evaporation in pools during hot months?

Using a pool cover is an effective way to reduce water evaporation during hot months. Pool covers act as a barrier between the water surface and the atmosphere, limiting the exposure of the water to air. This significantly decreases the rate of evaporation because the cover traps moisture and keeps heat in, creating a more stable temperature and reducing the impact of wind, which can exacerbate evaporation.

While increasing water levels might seem like a viable option, it does not directly address evaporation and may lead to additional water loss. Adding more chemicals does not influence evaporation rates and could lead to chemical imbalances in the pool. Similarly, maintaining ventilation is important for air quality and preventing algae growth, but it does not serve to minimize evaporation. Therefore, utilizing a pool cover is the most effective strategy in this context.
