    • Convenient and easy to use
    • 73% available chlorine
    • Will not cause overstabilization

    How to use:
    Add the recommended dosage of this product during evening hours while the filter is running. Broadcast the product evenly over a wide area in the deepest part of the pool. Use a clean dry scoop to measure this product. DO NOT use the scoop for any other purpose. If any granules settle to the bottom of the pool use brush to disperse.

    Opening Your Pool:
    For best results, see the Water Balance section above before treatment. Always adjust and maintain pH in the 7.2 to 7.6 range. Follow SHOCK TREATMENT directions on this package. Allow 30 minutes for product to disperse. Test free available chlorine residual with a pool test kit. Repeat treatment as needed.

    Shock Treatment/Superchlorination:
    Every 7 days, or as necessary to prevent pool problems, shock treat/super chlorinate the pool by adding 9 to 18 ounces of this product per 10,000 gallons of water to provide 5 to 10 ppm available chlorine. Additional shock treatments may be required to correct problems which are caused by visible algae, high bathing loads, heavy wind and rainstorms. Additional shock treatments may also be required to correct problems such as unpleasant odors and eye irritation. Check the available chlorine with a suitable test kit.

    Algae Control:
    Follow SHOCK TREATMENT directions on this label. Add this product as close as possible to any algae on the sides or bottom of the pool. If necessary, repeat the treatment. 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 algaecide product regularly. Follow label directions on the algaecide.

    Expert Tip

    Additional shocking to keep water clean and clear is recommended after rain and heavy winds, high number of swimmers; increased water temperature and/or increased frequency of pool usage.
