The biocidal properties of calcium hypochlorite are due principally to hypochlorous acid, which kills bacteria, algae, and other microorganisms. Hypochlorous acid is more effective as a biocide than hypochlorite ion. Because a residual level of FAC can be maintained with the use of calcium hypochlorite, it is classified as a primary sanitizer.
