A pool water treatment chemical designed to gather small, suspended particles in pool water, aiding their removal. These particles, often too fine to be effectively filtered, cause cloudiness. The treatment acts by binding these microscopic contaminants together, forming larger clumps that are then easily trapped by the pool’s filtration system or settle to the pool floor for vacuuming.
Maintaining water clarity is vital for aesthetic appeal and safety. Clear water allows for better visibility, reducing the risk of accidents. Furthermore, the treatment enhances the effectiveness of sanitizers, such as chlorine, by removing organic matter that would otherwise consume the sanitizer. Historically, various substances, including alum, have been used for similar purposes, but modern formulations offer improved performance and ease of use.
