A composition (98) for the treatment of a liquid, particularly a body of water, such as a swimming pool, spa, or the like. The composition (98) includes calcium hypochlorite (96), a water soluble zinc salt for controlling algae, and sodium aluminate as an agglomerating agent that may safely be combined with calcium hypochlorite (96) and the zinc salt. A floating chemical dispenser (10.1, 10.2) for containing and dispensing chemicals to treat a body of water. The dispenser (10.1, 10.2) includes an upper end float (18), a container (20) adapted to contain chemicals, the container (20) removably joined with the upper end float (18), and a free end float (94) joined with the container (20). The free end float (94) is configured so that a central axis (B) of the container (20) and upper end float (18) is not substantially orthogonal to a surface of the water. |
