Granular Shock Pouches 4.8kg (16x 300g Sachets)

Why Choose Granular Shock Pouches?

Granular Shock, also known as Calcium Hypochlorite, is essential for destroying chloramines (chlorine bonded bacteria) that build up in a chlorine pool, along with harmful bacteria and algae. Regular use helps to maintain crystal clear water.

We recommend removing any swimming pool cover when using shock chlorine.

The shock pouches are a great way to keep the chlorine fresh, especially over winter when usage may decrease.

Application Instructions

• Step 1: Maintain pH levels within the ideal range of 7.2 – 7.6. If the level is out of range, adjust accordingly.
• Step 2: Maintain free chlorine residuals routinely in the 1 – 3mg/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.
• Step 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 clean warm water. Stir well to ensure the product is fully dissolved. Add the resulting solution to the pool while the pump is turned on, preferably near the water inlets to aid distribution.
• Step 4: Repeat the dose/application if necessary to achieve the desired chlorine level.
• Step 5: After using this product, pool water may become temporarily cloudy, so keep the filtration pump running until it clears.
• Step 6: After shock treatment, allow the chlorine to drop below 5mg/l before bathing resumes, and in any event, wait for at least 30 minutes before bathing recommences.
