Abstract
Metal-containing biocides for treating swimming pool water, spas, cooling towers, or other industrial applications without staining are disclosed. The biocidal compositions include a source of metal and a polymeric sequestering agent. The polymeric sequestering agent may be a water-soluble anionic or cationic polymer. Conventional sequestering agents may also be included in the composition.
