Swimming Pool Algae Guard is a specially formulated chemical treatment used to prevent and control the growth of algae in swimming pools. It works by disrupting the cellular processes of algae, stopping their development and reproduction. Typically available in liquid form, algae guard is added directly to pool water and is compatible with chlorine and other sanitizers. It helps keep the water clear, hygienic, and free of green, yellow, or black algae. Regular use of algae guard reduces the need for intensive cleaning, improves water circulation, and enhances the overall appearance and safety of the pool.
