Acti HP Shock Granules. These non stabilised chlorine granules are ideal for shock dosing or regular oxidisation of swimming pool & spa water. They may also be used for routine swimming pool disinfection. By ‘shocking’ your pool you actually increase the chlorine level. The purpose of this is to raise the chlorine level to remove bacteria or any organic matter from the water. This process should occur weekly, in peak use it should be shocked more regularly. Using tablets that release chlorine slowly does not provide your pool with sufficient amounts of chlorine to shock the water.

Application Instructions: Maintain pH levels within the ideal range of 7.2 – 7.6 and 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 a full shock treatment.
Pre-dissolve this product in a clean plastic container at a maximum rate of 100g per 10 litres (2.2 gallons) of warm water. Stir well to the ensure the granules are fully dissolved. Add the resulting solution to the pool whilst the pump(s) are turned ‘on’ preferably near the water inlets to aid distribution.
After using the shock granules the 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 5ppm before bathing recommences, and in any event wait for at least 30 minutes before bathing recommences.
IMPORTANT: Wear eye and face protection and ensure granules are not blown back into your face.
