Abstract
A water treatment composition for treating a body of water is provided that provides visual feedback to the end-user of the effectiveness of the composition. The composition contains a majority of calcium hypochlorite particles; and an effective amount of colored particles containing an oxidizable pigment oxidizable dye and a water soluble material. The colored particles release the oxidizable dye to the body of the water to provide a transient color to the recreational water during dissolution of the composition in the body of water, the transient color providing a visual cue to the end-user signaling of the biocidal activity of the composition. Also provided is a method of applying the water treatment composition to recreational water.
