Compositions for cleaning, sanitizing and maintaining contained bodies of
water such as swimming pools, wading pools, fountains, ornamental ponds,
etc. The compositions include pre-determined percentages of hydrates of
copper sulfate, zinc sulfate, and aluminum sulfate by weight. The
composition uses hydrates of copper, zinc and aluminum sulfates instead
of the anhydrous metal salts. The hydrate forms can be mined,
transported, processed, mixed and packaged without climate controlled
conditions necessary for anhydrous metal salts. Hydrates in the
composition can gain additional water molecules or lose attached water
molecules during manufacture, processing, transportation or use of the
composition, without negatively affecting the physical format of the
composition or reducing its effectiveness. The compositions reduce
amounts of chlorine and an amount of labor associated with the cleaning,
sanitization and maintenance of contained bodies of water.
