Abstract:
1. A method for removing phosphates from a body of water having a surface and a floor, the method comprising the steps of: a) forming a diluted phosphate scavenging composition by feeding a concentrated phosphate scavenging composition including aluminum chlorohydrate from a container and water under pressure from a water hose into a mixing chamber of a hand held hose end sprayer attached to the container and the water hose; b) spraying the diluted phosphate scavenging composition from the hand held hose end sprayer onto the surface of the body of water; c) allowing the diluted phosphate scavenging composition to remain in the body of water for a period of time sufficient to interact with the phosphate in the body of water and carry it to the floor of the body of water as a sediment; and d) removing the sediment from the floor of the body of water.
