Maintenance Care:
Adjust pH (7.2-7.4) and alkalinity (80-150 ppm) 1-2 times weekly. Shake before using. Initially apply this product at the rate of 1 ounce for every 100 gallons of water. Weekly apply 1-2 ounces for every 500 gallons of water. Pour directly into the water with the pump circulating at the lowest setting. After application, avoid superchlorinating (shocking) the water for 24 hours to insure maximum effectiveness of this product. If spa foams after application that is an indication the product is working and will subside. Rinse filter once a month.
Phosphate Reduction
Rinse or clean prior to use. For all spa sizes, if phosphate levels exceed 1,000 ppb add 8 ounces directly to the spa water with the pump running. Swim Spas, double the dose. If the water becomes cloudy or hazy after use that is an indication the product is working and will go away as the filter removes the suspended particles. After 48 hours, rinse filter to remove phosphates from the water. Retest phosphate levels after one week. Rinse filters once a month.
