ABSTRACT:
The present invention is a method of treating a standing water system comprising the administration to the standing water system of an admixture comprising calcium hypochlorite and borate salts. The method of treating a standing water system provides free chlorine to the system more efficiently than prior art methods, stabilizes the pH of the standing water system, and reduces the undesired side effects of the addition of calcium hypochlorite alone.
