Shock Treatment/Superchlorination:

For best results, see "Water Balance" and "How To Use" sections on package before beginning treatment. Every 7 days, or as necessary to prevent pool problems, shock treat/superchlorinate the pool by adding one bag 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. Re-entry into treated pools is prohibited above 4 ppm due to risk of bodily harm.
