Some other pool shocks have a lower percentage of active ingredient with a higher percentage of inert ingredients which reduce the amount of chlorine sanitizer that is ultimately added to your pool.

Don't settle for anything less when looking for a pool shock to effectively treat pool problems like algae blooms and swimming accidents fast. As the chlorine dissolves in the water, it forms hypochlorous acid which is what kills and eradicates algae and bacteria.

Usage Directions for Swimming Pools:

  • Add the recommended dosage of In The Swim Super Pool Shock during the evening hours while the filter pump is running.
  • When adding to your pool, broadcast 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 a brush to disperse.

Superchlorination Usage Directions for Swimming Pools:

  • Every 7 days, or as necessary to prevent pool problems, shock treat/super chlorinate the pool by adding 9-18 ounces of In The Swim's Super pool Shock 1lb bags per 10,000 gallons of pool water to provide 5-10 ppm available chlorine.
  • Additional shock treatments may be required to correct problems which are caused by visible algae growth, high bathing loads, heavy wind, rainstorms, unpleasant odors, and eye irritation. Check the available chlorine level with a suitable test kit.
  • To prevent possible staining or bleaching, take the following steps immediately after treatment: Thoroughly clean the pool by brushing the surface of algae growth, vacuum, and cycle through the filter.
  • Re-entry into treated pools is prohibited above 4 ppm due to risk of bodily harm
