Abstract:
1. A method cleaning and sanitizing a contained body of water sanitized with chlorine, comprising: measuring a pH level of water in the contained body of water; adjusting the measured pH, if necessary, to fall within a specified pH range; preparing a pre-determined amount of a composition based on an amount of water in the contained body of water, wherein the composition comprises 40% to 50% copper sulfate, 40% to 50% zinc sulfate; and 10% to 20% aluminum sulfate, by weight; adding the prepared amount of composition to the water of the contained body of water; and circulating the water in the contained body of water for a pre-determined amount of time is disperse the composition, thereby cleaning and sanitizing the water in the contained body of water, wherein the composition cleans and sanitizes the water in the contained body of water, inhibits photo-degradation of any chlorine added to the water from sunlight thereby further reducing an amount of chlorine necessary to sanitize the water in the contained body of water, maintains the chemical properties of the water within pre-determined pH limits and causes debris and other particulate matter to sink to a bottom of the water for easy removal.
