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.
