Application Instructions for Shock 'n' Floc

  1. Maintain pH levels within the ideal range 7.2 - 7.6. If the level is not in the range, adjust.
  2. Maintain free chlorine residuals routinely in the 1 - 3 mg/l (ppm) range. Shock or oxidising procedures are recommended either weekly or fortnightly with a maximum of 10 mg/l (ppm) for a full shock treatment.
  3. Pre-dissolve the shock chlorine (non stabilised granules) in a clean plastic container at a maximum rate of 100g of product per 2.2 gallons (10 litres) of water. Stir well to ensure Shock 'n' Floc is fully dissolved. Add the resulting solution to the pool whilst the pump(s) are turned 'on' preferably near the water inlets to aid distribution.
  4. Repeat the dose / application if necessary to achieve the desired level.
  5. After using shock 'n' floc granules, pool water may become temporarily cloudy, so keep the filtration pump running until it clears.
  6. After shock treatment procedures, allow the chlorine to drop below 5 ppm before bathing recommences, and in any event wait for at least 30 minutes before bathing recommences.
