The primary method to control algae growth in pool water is maintaining proper sanitizer levels. Sanitation is crucial because it ensures that harmful microorganisms, including algae, are kept at bay. Chlorine is commonly used as a sanitizer in pools, and it works by oxidizing contaminants and disinfecting the water. When sanitizer levels are kept within the recommended range, it effectively prevents algae blooms and ensures the overall health of the pool water.

In addition, maintaining appropriate sanitizer levels contributes to other aspects of pool maintenance, such as preventing bacteria and viruses, which helps create a safe swimming environment. Conditions of low sanitizer can lead to imbalances that allow algae to thrive. Regular testing and adjustment of sanitizer levels are therefore fundamental practices for pool owners and operators.

The other methods mentioned do not effectively address the primary issue of algae control. Regularly changing the water can be impractical and costly while avoiding direct sunlight exposure is often not feasible, as sunlight is a natural part of the environment. Using more chemicals than necessary may cause imbalances in water chemistry, leading to further issues rather than solving the algae problem.
