This product quickly lowers excess chlorine and bromine levels in swimming pools and spas. It can be used any time your chlorine is higher than recommended in your swimming pool and is commonly used after super-chlorination or treatment for algae removal.
Dosage: 2.4 ounces for 10,000 gallons of pool water to reduce by 1 ppm. Add directly to pool by applying around the edge of the pool. Keep the pump on and water circulating. Do not add the product through the skimmer.
Active Ingredient: Sodium Thiosulfate.
Directions for Use: Allow super-chlorination treatment at least 8 to 12 hours to oxide organic wastes and chloramines from the pool water before adding chlorine neutralizer to lower the available chlorine to the level for swimming (typically between 2 to 5 ppm). Measure the available chlorine in the water immediately before adding chlorine neutralizer. This must be done in order to determine the correct dosage amount. Calculate the ppm available that must be removed from the pool. For example: the available chlorine reading in the water minus the desired available reading in the pool. A dose of 2.4 ounces by weight is need to reduce the chlorine reading by 1 ppm per each 10,000 gallons of water in the pool.
