Why is it important to maintain proper water levels in a pool?

Maintaining proper water levels in a pool is essential primarily because it ensures proper skimming and circulation, as well as prevents equipment damage. When the water level is too low, it can prevent skimmers from functioning effectively, which means debris and contaminants may not be adequately removed from the water surface. This compromise in circulation can lead to poor water quality and imbalance in chemicals, as well as promote algae growth and other issues related to cleanliness and sanitation.

Additionally, when the water level drops too low, the pool's circulation system may run dry, causing unnecessary strain and potential damage to the pump and other equipment. Keeping the water at the recommended level helps to protect this equipment and maintains an efficient and effective filtration and circulation system.

While factors such as water temperature, algae growth, and clarity are important for pool maintenance, they are secondary to the critical function of ensuring the water level supports the pool's operational systems effectively.
