These granules are rapid dissolving, long lasting and have little effect on the pH of the water.? They are suitable for shock dosing small above ground pools.? You can find dosing amounts below.
Key Features
Granular chlorine has little effect on the pH level of the water. These stabilised chlorine granules are ideal for regular dosing of your swimming pool or spa, to produce free active chlorine which kills bacteria and other potentially harmful organisms.
Application Instructions
1. Maintain pH level within the ideal range of 7.2 ? 7.6. If outside this range please use our PH plus or PH minus products to adjust for the best results.
2. Maintain free chlorine residuals for spas within the range 3 ? 5mg/l (ppm).? For swimming pools it should be 1 – 3mg/l (ppm). Freshly filled spas require an initial shock or start up dose of chlorine: 50mg/l (ppm) for 1 hour or 20mg/l (ppm) for 2 hours.
3. This product may be applied directly to pools or spas where temperatures exceed 20? degrees C. If below this temperature or in doubt it is recommended to pre-dissolve in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1ltr) in water. Stir well to ensure product is fully dissolved. Add the resulting solution to the spa or pool whilst the pumps are turned ?on?.
4. Repeat dose application if necessary to achieve the required levels.
5. It is recommended that you periodically (e.g. weekly or after heavy spa use) shock dose your spa to eliminate any excess contamination.

Alan Doleman –
Using this allowed me to keep the pool clean all summer without having to empty and refill, just kept topping up and redosing.

Great buy
cristhian andres –
i liked the price as it will last me 3 years as i only have a 170 gallon hot tub so don’t need the amount a large pool would, as i intend to have hot tubs for years to come i will be making a good saving with buying this 5kg tub instead of the 1kg or 500gram tubs that are generally bought.it does its usual high quality job and keeps the water in great condition
