How to use: do not pre-mix this product before adding it to your pool. Only add this product directly to your pool or skimmer. Use entire contents when opened.
Method for dosing directly into pool: add the recommended dosage of this product during evening hours while the filter pump is running. When adding this product to your pool, broadcast the product evenly over a wide area in the deepest part of the pool. If any granules settle to the bottom of the pool, use brush to disperse.
Method for skimmer addition: make sure that filter pump is on and properly recirculating through skimmer. Empty skimmer of all chemicals and/or debris. Contamination may cause an explosion or the release of toxic gases. Do not use this method when an automatic chemical dispensing device (e.g. feeder) is present. Pour this product slowly into skimmer, making sure that the material is drawn into the system at the same rate: do not allow this material to accumulate as toxic gases may be generated.
Water balance: for best product performance, swimmer comfort and crystal clear water, use Hth pool care products to maintain the following water balance.
Acceptable range for balance.
Total alkalinity 60-120 ppm.
Calcium hardness: above 200 ppm.
Available chlorine: 1-4 ppm.
Follow label directions for each product and allow each product to dissolve and disperse before adding additional products to the pool. Use a reliable test kit that measures all these ranges. Re-entry into treated pools is prohibited above levels of 4 ppm for risk of bodily injury.
Opening your pool: for best results, see the "water balance" section above before treatment. Adjust and maintain ph in the 7.2 to 7.6 range. Allow the ph adjusters to dissolve and disperse before adding this product to the pool.
1. Follow "pool shock treatment" directions on this package.
2. Allow 30 minutes for product to disperse.
3. Test free available chlorine residual with a pool test kit.
4. Repeat dosage, as needed, until the free available chlorine residual is 1-4 ppm. Re-entry into treated pools is prohibited above levels of 4 ppm for risk of bodily injury.
As a preventative treatment, you should shock treat your pool once a week to prevent pool problems. In addition to weekly shock treatment, you should shock treat to remedy problems which occur when bather loads are high, water appears hazy or dull, unpleasant odors or eye irritation occur, after heavy wind and rainstorms, or if algae does develop with resulting green color and slimy feeling walls.
Pool shock treatment: add the recommended dosages of this product while the filter pump is running. Adjust and maintain pH to 7.2 to 7.6 with Hth pH Plus� or Hth pH minus. Follow label directions. When adding this product to your pool, broadcast this product evenly over a wide area of the deepest part of the pool.
Dosage rate: shock treatment / super.
Chlorination: for best results, see "water balance" and how to use" section above before treatment. Every 7 days, or as necessary to prevent pool problems, shock treat/super chlorinate the pool by adding 16 to 32 ounces (one to two bags) per 11,500 gallons of water to yield 5 to 10 ppm available chlorine by weight. Re-entry into treated pools is prohibited above levels of 4ppm for risk of bodily injury.
1. Follow "pool shock treatment" directions on this label.
2. Add this product as close as possible to any algae on the sides or bottom of the pool.
3. Do not enter pool until the free available chlorine residual is 1-4 ppm.
4. If necessary, repeat the treatment.
5. To prevent possible staining or bleaching, take the following steps immediately after treatment: thoroughly clean pool by brushing surface of algae growth, vacuum and cycle through filter. For preventative algae control, use your preferred Hth algaecide product regularly.
