This product is used to control the growth of algae in decorative fountains that do not contain fish. It is also used to control algae, bacteria, and fungi in recirculating commercial and industrial water cooling towers and recirculating cooling systems.

WATER COOLING TOWERS: Prior to the use of this product in water cooling towers, clean the systems to remove algal growth, microbiological slime, and other deposits. Then make an initial slug addition of 4 to 10 fluid ounces of this product per 1000 gallons of water to provide 32 to 80 ppm this product, based on the total weight of water in the system. Repeat initial dosage until control is evident. Make subsequent slug additions of 1.0 to 10.0 fluid ounces of this product per 1000 gallons of water (8 to 80 ppm) every 2 to 5 days or as needed. The frequency of addition depends upon the relative amount of bleedoff and the severity of the microbiological problem. Make slug additions into the sump of water cooling towers.

DECORATIVE FOUNTAINS: This product is used to control the growth of algae in decorative fountains that do not contain fish. Manually clean heavy growths of algae prior to treatment. Fountains with just visible algae growth require an initial dose of 5 to 8 fluid ounces of this product per 1000 gallons of water. To treat a freshly cleaned and filled fountain, add 3 to 5 fluid ounces of this product per 1000 gallons of water. For maintenance dosages, add 1 to 2 fluid ounces of this product per 1000 gallons of water every 5 to 7 days as needed. Make sure this product is added at a point where it can be uniformly distributed. This product may be used in fountains treated with chlorine chemicals, but do not mix this product with concentrated dry or liquid chlorine products.

INDUSTRIAL AIR WASHING SYSTEMS: This product is used to control bacteria in industrial air washing systems that maintain effective mist eliminating components. Prior to its use, clean the systems to remove bacterial slime and other deposits. Make an initial slug dose of 14.8 to 24.7 fluid ounces of this product per 1000 gallons of water. Repeat initial dosage until control is evident. Make subsequent slug additions of 10.1 to 24.7 fluid ounces of this product per 1000 gallons of water each 1 to 5 days, or as needed. The frequency of addition depends upon the relative amount of bleedoff and severity of the bacterial problem. Make slug additions into the sump or into the water collection trays of the airwash system.
