Granular Shock - A traditional shock treatment product, these calcium hypochlorite granules have an available chlorine level of on average 70% making them a good chlorine donor for pool water problem solving.Granular Shock Chlorine is very effective at restoring sparkling water from algae infestation.Granular Shock Chlorine can be added through the skimmer.Top Tip:As soon as possible after a thunderstorm shock dose your pool with a 5mg/l dose of Granular Shock Granules or Shock ‘n’ Floc Granules.The reason for this is that lightening creates nitrogen in the atmosphere and the rain washes this nitrogen into your pool. Nitrogen is plant food and algae thrive on it, so pool water can quickly turn green after a thunderstorm, a shock dose of chlorine can help prevent this.Application Instructions:1. Maintain pH levels within the ideal range of 7.2 - 7.6. If the level is not in this range, adjust accordingly.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 10mg/l (10ppm) for a full shock treatment.3. Pre-dissolve this product 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 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/application if necessary to achieve 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 procedures allow the chlorine to drop below 5ppm before bathing recommences and in any event wait for at least 30 minutes before bathing recommences.\n\n\n\n
