Abstract
Abstract A water treatment composition comprising a water soluble chlorine containing compound or blend of compounds, optionally cyanuric acid, a water insoluble fatty diamide synthetic wax, and optionally a molding lubricant is effective in inhibiting the growth of bacteria, algae and other plant life in water when the composition is blended together and shaped into dosage unit form. The composition maintains its configuration during exposure to water and retains undesirable insolubles, while permitting the leaching of chlorine from the unit by the action of water upon the composition.
