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.

It may seem expensive, but it does a great job chlorinating my 10 foot pool. I only need to add a little every few days to keep the test strips happy, so I envisage this amount is going to last me a few summers? Anyway, you have to have it, so might as well take the plunge lol 🙂

Instructions are a little difficult to figure out for amount to use.I have found this product at a significantly cheaper price in B&M and other shops.A good quality product. Does as it says once you have figured out the instructions.

Cleaned my pool quickly. Read instructions dont do it in a strong wind. Best to mix in a bucket of water in a garage or out the way as it has a strong smell. But it is the best i have used for doing the job
