Which factor can contribute to the development of algae in a pool?

Low levels of chlorination are a significant factor that can contribute to the development of algae in a pool. Chlorine is a crucial disinfectant that helps eliminate bacteria, viruses, and algae. When the chlorine levels are insufficient, it becomes less effective at preventing algae growth, allowing it to thrive. Algae can multiply quickly, especially in warm, sunlit conditions, leading to cloudy water and other water quality issues.

While excessively high pH levels can also promote algae growth, the presence of balanced chemical levels and frequent water circulation are integral practices that help maintain a clean and healthy pool environment. Maintaining the correct balance of chemicals, including the appropriate pH, helps to inhibit algae and other contaminants. Regular circulation allows for proper distribution of chemicals, further reducing the likelihood of algae outbreaks.
