Haviland Durachlor 3" Tablets

1. Before bathing, test water pH, chlorine residual, and total alkalinity using a suitable test kit. Adjust chlorine residual to 1-2 ppm. Use a chlorine stabilizer, especially outdoors to prolong chlorine residual. Maintain pH of water between 7.2-7.6 and total alkalinity between 125-175 ppm.
2. Place tablets in skimmer basket or suitable feeder to maintain chlorine level between 1 to 2 ppm. If chlorine residual is too high or low adjust number of tablets in skimmer basket or make necessary adjustments to feeder to maintain proper level. Under normal conditions 1 or 2 ounces of this product daily for each 10,000 gallons of pool water will maintain proper chlorine level. Do not place any other chemical with this product in the skimmer basket or feeder.
3. Weekly, superchlorinate water to 5 to 6 ppm using a suitable superchlorinating product. Follow directions on the product label for proper dosage. Avoid use of products such as body lotions that consume chlorine.
4. Reentry into treated pools is prohibited above levels of 3 ppm of chlorine.
