TCCA 90 Tablets are a solid form of Trichloroisocyanuric Acid used primarily for convenient and long-lasting disinfection of swimming pools, fountains, and water tanks. These slow-dissolving tablets steadily release chlorine into the water, killing harmful microorganisms such as bacteria, viruses, and algae while helping maintain a stable chlorine level over time. The tablets are typically placed in floaters, dispensers, or chlorinators for controlled dosing. Alongside disinfection, they also release cyanuric acid which stabilizes chlorine under sunlight. Regular testing of chlorine and pH levels is important when using TCCA tablets to ensure safe, balanced water and to avoid over-chlorination or chemical buildup.
