ABSTRACT:
The present invention comprises devices and methods for treating a standing water system comprising devices for the administration to the standing water system an admixture comprising calcium hypochlorite and borate salts and acids through a perforated distribution device. The method of treating a standing water system more efficiently provides free chlorine to the system, stabilizes the pH of the standing water system, and reduces the undesired side effects of the addition of calcium hypochlorite alone.
