ABSTRACT:
A composition and method are provided for clarifying and deodorizing a standing body of water such as fresh and salt water pools and water of spas, cooling towers, lakes and ponds such as aquaculture ponds. The composition contains by weight about 20.26% of a fermentation supernatant from a Saccharomyces cerevisiae culture, about 0.1% sodium benzoate, about 0.01% imidazolidinyl urea, about 0.15% diazolidinyl urea and about 9% non-ionic surfactant. Preferably, anionic and cationic surfactants and urea are absent from the composition. The composition may also contain about 0.05%, by weight, calcium chloride. The method is carried out by adding a solution of the composition to a body of water to provide in the water by weight about 0.02% to about 0.1% of a fermentation supernatant from a Saccharomyces cerevisiae culture, about 0.00005% to about 0.0001% sodium benzoate, about 0.000002% to about 0.00001% imidazolidinyl urea, about 0.00003% to about 0.00015% diazolidinyl urea, about 0.002% to about 0.009% non-ionic surfactant, and about 0.000005% calcium chloride when present.
