Doheny's 1 in Chlorine Tabs, 48 lb

DIRECTIONS FOR USE:

For Swimming Pool Disinfectant: When used as directed, this product is effective as a swimming pool water disinfectant. The dosage necessary for your pool will change considerably depending upon those factors that burden the disinfection system. Some of the factors that will vary the required dosages are water temperature, bather load, exposure to windblown debris, thunder or rain storms and length of filtration cycle.

For Start up of Newly Filled Pools: Before using this product, make sure that the filtration system is clean and operating properly. Adjust the pH of the water to the 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. To initially achieve 1-3 ppm available chlorine, add 1.25 oz. product per 1,000 gallons of water. Add 1/4 oz. product per 1,000 gallons of water daily or as needed to maintain that level. Ensure all pool equipment is working properly. Backwash the filter system following manufacturer’s directions. Adjust pH to between 7.2-7.6. Add stabilizer to establish a minimum level of 30-40 ppm to reduce degradative effects of sunlight upon the chlorine residual. Check for metals. Before using this product, add stain and scale inhibitor to prevent staining of pool surface due to metals. When using other products as outlined in the directions for this product, always follow directions on those products. With pump running , place four (4) tablets per 10,000 gallons pool water every other day into a suitable feeder or directly into a skimmer basket. Repeat additions until a residual of 1-3 ppm chlorine is established as determined by the use of a test kit. Regular use of a test kit is necessary to determine when it is necessary to add another dose of this product to maintain a residual of 1-3 ppm avaiable chlorine in the pool water. After use of this product it is recommended that a preventative algae treatment be added on a weekly basis.

For Superchlorination: The pool water should be superchlorinated or shocked every seven days or whenever the combined chlorine level is above 0.5 ppm (mg/L). Combined chlorine is the difference between total and free chlorine, as measured by a suitable test kit. Add a sufficient amount of an appropriate shock product directly to the surface of circulating water to raise the available chlorine level to 5-6 ppm (mg/L), based on test kit readings. If the combined chlorine reading is not below 0.5 ppm (mg/L), repeat the shock treatment described above. For example, the addition of 10 ounces of sodium dichloro-s-triazinetrione per 10,000 gallons of water (7.5 grams per 1,000 liters) will provide approximately 5 ppm (mg/L) of available chlorine. If the combined chlorine reading is not below 0.5 ppm (mg/L) and the water has not been restored to its normal clarity, repeat the shock treatment described above.p>

NOTE: Reentry into treated swimming pools is prohibited above levels of 3 ppm of Chlorine due to risk of bodily injury.

How to Determine Pool Capacity in U.S. Gallons

Use the Appropriate Formula Below

Rectangular or Square: Length x Width x Average Depth x 7.5 = Total Gallons

Round: Diameter x Diameter x Average Depth x 5.9 = Total Gallons

Oval: Maximum Length x Maximum Width x Average Depth x 6.7 = Total Gallons

Storage and Disposal

Pesticide Storage: Do not contaminate water, food or feed by storage or disposal. Store in a dry, cool and well ventilated area. Avoid moisture getting into container. Keep off wet floors. ln case of spillage, wash with large amounts of water. After each use, keep container tightly closed. Oxidizing material. Keep away from flames, sparks and all sources of heat. Avoid contact with organic material.

Pesticide Disposal: Pesticide wastes are acutely hazardous. lmproper disposal of excess pesticide, spray mixture or rinsate is a violation of Federal Law. lf these wastes cannot be disposed of according to label instructions, contact your State Pesticide or Environmental Control Agency, or the Hazardous Waste representative at the nearest EPA Regional office for guidance.

Container Handling: Nonrefillable container. Do not reuse or refill this container. Offer for recycling, if available. Triple rinse container (or equivalent) promptly after emptying.

Emergency Handling: ln case of contamination or decomposition do not reseal container. lf possible, isolate container in open well-ventilated area. Flood with large volumes of water. Dispose of contaminated material in an approved landfill area.

Spills: When handling or dealing with spills, use impact-resistant goggles with side-shields, or face shield; body-covering clothes, including impervious rubber or plastic gloves and boots; use a dust respirator if dusting occurs. Sweep up dry spills and dispose of as described for pesticide disposal. If drum contents are contaminated or decomposing, do not reseal container; isolated sealed drum in the open or in well-ventilated area; flood with large volumes of water if necessary
