Usage Directions

This product is intended for use in controlling bacteria and algae in swimming pools. This product should be added directly to the surface of circulating water according to the directions. Each ounce of this product will provide about 0.4 ppm (mg/L) of available chlorine to 10,000 gallons of water. Reentry into treated swimming pools is prohibited above levels of 4 ppm of chlorine.

How to Use: Add dosage of this product during evening hours while filter is running. When adding this product to your pool, broadcast the product evenly over a wide area in the deepest part of the pool. Use entire contents when opened. If any granules settle to the bottom of the pool use brush to disperse.

Start Up: Before using this product, make sure that the filtration system is clean and operating properly. Adjust the pH of the water to a range of 7.2-7.6 using suitable products and a reliable test kit. Adjust the alkalinity of the water to a minimum of 125 ppm (mg/L), based on the test kit reading. Add a sufficient amount of this product directly to the surface of circulating water to raise the free chlorine level in the water to 5-6 ppm (mg/L), based on the test kit reading. As a guide, for swimming pools addition of 10 ounces of this product for each 10,000 gallons of water will increase the free residual chlorine by 4 ppm (mg/L).

Shock Treatment: Super chlorination: In extremely hot weather, when many people use the pool, when water becomes hazy or after heavy rains, a shock dosage of chlorine may be obtained by spreading this product over surface pool water. 14 ounces of this product per 10,000 gallons of pool water provides approximately 6 ppm of chlorine. Note: Do not use pool until chlorine residual falls below 4 ppm.

Maintenance Treatment: Add this product daily or as needed to maintain the free chlorine residual in the water at 1-3 ppm (mg/L) as indicated by a reliable test kit. Each ounce of this product will provide about 0.4 ppm (mg/L) of available chlorine to 10,000 gallons of water. Weather and usage effect sanitizer levels. Maintain the pH at 7.2-7.6 and the alkalinity at a minimum of 125 ppm (mg/L). As a guide for swimming pools, addition of five ounces of this product for each 10,000 gallons of water will increase the free residual chlorine by 2 ppm (mg/L).
