How to apply chlorine shock granules:

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