Blue Horizons Granular Shock Chlorine - Tub of 2kg

Directions Maintain pH levels within the ideal range of 7.2-7.6. If the level is not in this 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 10mg/l (ppm) for a full shock treatment. Pre-dissolve this product in a clean plastic container at a maximum rate of 100g of product per 2.2 gallon (10 litres) of water. Stir well to ensure product 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 dose/application if necessary to achieve the desired level. After using the product, pool water may become cloudy temporarily 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.
