What is the primary role of a pool cover?

The primary role of a pool cover is to keep debris out and reduce evaporation and chemical loss. When a pool cover is in place, it prevents leaves, dirt, and other debris from entering the water, which helps maintain water clarity and reduces the frequency of cleaning needed. Additionally, a cover significantly minimizes evaporation, which can help retain water levels and conserve water. By limiting evaporation, a cover also helps to maintain the balance of chemicals in the water, reducing the need for constant chemical adjustments, which contributes to a more stable and manageable pool environment. Moreover, while pool covers can provide some assistance in other areas such as heating through passive solar gain or offering a degree of safety, their main purpose primarily centers around protecting the pool from external contaminants and conserving water and chemicals.
