Calcium Hypochlorite™
Water Clarity Increaser
This calcium hypochlorite product is a dry granular free flowing material that contains a minimum of 65% available chlorine. It provides a rapid source of a chlorine-containing disinfectant that protects the pool against the growth of bacteria and algae to help keep the pool in a sanitary condition. Pool water is subject to a buildup of a wide variety of organic contaminants including swimmer wastes, such as perspiration, ammonia compounds, and natural and synthetic oils and lotions. If left untreated, the buildup of these contaminants can lead to the development of noxious odors, irritating water, and unsightly water clarity problems. These organic wastes serve as nutrients for bacteria, algae, and other organisms, and should be removed from the pool on a regular basis to prevent their build up. This product will effectively reduce organic contamination in swimming pool water resulting in increased water clarity.

Directions for Use
For any application method you choose: No one can be in the pool when chemicals are being added directly to the pool. Do not mix this product with other chemicals, including any other pool chemicals of any kind, such as other disinfection or “shock” products. Mixing could cause a fire or explosion. Always add this product into large quantities of water to fully dissolve. Never add water into product. Make sure to keep the pump and filter running during application and for at least 6 to 8 hours after application to allow for the best product dispersion. For best results, test your pool water prior to addition of this product and maintain pool water parameters in the ranges noted below.
This product will raise the pH of pool water. For best results, test your pool water prior to addition of this product. If your pH measures 7.4 or higher, adjust it downward so that it is between 7.2 to 7.4. This will help avoid clouding of water and allow for faster dispersion of the product.
Routine Chlorination:
The pH, total alkalinity, water hardness, and stabilizer concentration should be maintained at values recommended in Table 1 under “Regular Treatment for Pools in Use.” Actual dosages of this product required to maintain the desired free chlorine residual will vary with sunlight, water temperature, bathing load, stabilizer concentration, water balance, and other factors. Use a test kit frequently to determine and maintain the proper free chlorine residual. Do not enter the pool until the free chlorine residual has dropped to 4.0ppm or less as measured using your test kit. Add 3-4 ounces of this product (1-2 ounces in stabilized pools) per 5,000 gallons of water daily or as often as needed to maintain the desired free chlorine residual whether the pool is in use or not. For small changes in free chlorine residual once a free chlorine residual is detected, the addition of 1 ounce of this product to 5,000 gallons of water will raise the free chlorine residual approximately 1.0ppm.
Shock Treatment/Superchlorination:
Adjust pH between 7.2 and 7.4 prior to shocking or superchlorination. Add this product at night or when the pool is not in use. To prevent pool water problems, shock at least once per week during periods of heavy use or when water temperatures are above 80°F and once every two weeks in residential pools receiving normal usage. Maintain operation of the pump and filter. Do not enter the pool until the free chlorine residual has dropped to 4.0ppm or less as measured using a suitable test kit. Between treatments with this product, continue to maintain the proper water balance and sanitizer level in your pool as recommended on the label of your normal pool sanitizer. Add 10 ounces of this product to every 5,000 gallons of water to yield 5-10ppm available chlorine.
