Abstract:
The present invention provides a composition for treating recirculating or stagnant water. The composition contains a phosphorus-containing compound, which is metaphosphate compound, a polyphosphoric acid or a polyphosphate, and one or more zinc compounds. The phosphorus-containing compound is a compound which is not readily hydrolyzable to an orthophosphate. In another aspect of the present invention, provided is a method of controlling algae in a body of recirculating or stagnant water using the composition.

Claim (Index 1):
A method of controlling algae in a body of recirculating or stagnant water, comprising the steps of:\n a) providing a body of recirculating or stagnant water containing algae; and b) adding to said body of recirculating or stagnant water an effective amount of a composition comprising a phosphorus-containing compound being sodium hexametaphosphate, and one or more water soluble zinc salts, wherein the phosphorus-containing compound is present in an amount effective to enhance algaestatic activity of the water soluble zinc salts and is a compound not readily hydrolyzable to an orthophosphate, the amount effective is at least about 2 ppm for the phosphorus-containing compound, and the weight ratio of zinc ion from the water soluble zinc salts to the phosphorus-containing compound is from about 2:1 to about 1:5.
