Abstract

A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.
