Unstabilised chlorine granules (65% available calcium hypochlorite)
Maintain PH levels within the ideal range 7.2 - 7.6. If the level is not in the range, adjust. 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 full shock treatment.
Pre-dissolve the granules in a clean plastic container at a maximum rate of 100g of product per 10 litres of water. Stir well to ensure shock 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. Repeat the dose / application if necessary to achieve the desired level.
After using shock granules, pool water may become temporarily cloudy, so keep the filtration pump running until it clears.
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.
DOSAGE INSTRUCTIONS: -
Daily dose rates routine chlorination - 5g per day per m³ of water
Shock chlorination - 15g per day per m³ of water
