What should be done if algae is present in a pool?

When addressing the presence of algae in a pool, increasing the pump's run time is a highly effective measure. The pump plays a crucial role in circulation, filtration, and maintaining water chemistry. By running the pump longer, you enhance the filtration process, allowing it to remove suspended particles, including algae.

Moreover, a longer pump run time ensures that any added sanitizers or algaecides can be properly distributed throughout the water. This helps to maximize their effectiveness in eliminating the algae. Good circulation is essential because algae can quickly multiply in stagnant water, and improved circulation allows the chemicals to thoroughly mix and reach all areas of the pool.

In contrast, stopping the use of sanitizer can exacerbate the problem since the lack of disinfection can lead to further algae growth. Simply adding more algaecide without proper brushing may not effectively remove the algae, as brushing helps to break apart clumps and facilitates the chemical's work in killing the algae. Closing the pool for several days is also not a practical solution, as it stops all water treatment efforts and can lead to more significant algae blooms. Properly managing pump run time is therefore an essential part of effective pool maintenance and algae control.
