What is one benefit of using a pool cover besides reducing evaporative loss?

Using a pool cover offers multiple benefits beyond minimizing evaporative loss, one of which is preventing debris accumulation. By covering the pool when it is not in use, leaves, dirt, and other debris are less likely to enter the water, which can lead to a cleaner pool and reduce the need for manual cleaning. This also minimizes strain on filtration systems and helps maintain clearer water, contributing to improved water quality and clarity.

The other options present varying concepts that do not directly relate to the benefits of a pool cover. For instance, while a cover can enhance the aesthetic value of a pool area, this is not as practical or measurable as the functional benefit of keeping debris out. Similarly, a pool cover does not inherently increase chlorine levels; the chemical balance is influenced by usage and maintenance, not the presence of a cover. Finally, a pool cover does not decrease the actual size of the pool, although it may create an optical illusion of a space that appears smaller when covered.
