Abstract: A solid formulation for use with sodium chloride and a chlorine generator to provide safe, clean chlorinated recreational water. The formulation comprises a chlorine stabilizing agent and a phosphate remover agent. An enhanced salt comprising a chlorine stabilizing agent, a phosphate remover agent and sodium chloride is also described. The formulation and enhanced salt can also contain a metal chelating agent and a pH balancing agent. A cleaning agent may also be included. A fast dissolving sodium cyanurate compound is used for the chlorine stabilizing agent. A method, kit, and system for providing safe, clean chlorinated recreational water are also disclosed.

Abstract: An enzyme-based aqueous cleaning and/or water clarifying solutions that provide improved cleansing and water clarifying capabilities and are exceptionally stabile to bacterial contamination. The invention also relates to the treatment of aqueous bodies and solid surfaces with the enzyme-based compositions of the invention in order to control the presence of contaminants. The objectives of the invention are achieved by including a small amount of a saponin in an aqueous enzyme-based composition containing a bacterial inhibiting stabilizer.
