Blue Horizons Shock Pot - Calcium Hypochlorite with 65% available chlorine. These non stabilised chlorine granules are ideal for shock dosing or regular oxidisation of swimming pool water. 

Application Instructions for Shock Chlorine Granules

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 for swimming pools and 3-5mg/l (ppm) for spas/hot tubs.  Maintain bromine levels in the range pools/spas 3 - 5mg/l (ppm). 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 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.
4. After using shock granules, pool water may become temporarily cloudy, so keep the filtration pump running until it clears.
5. 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.
