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.

Bought a used car from a dog owner and so I used a few of these diluted and left in car overnight to kill the doggy aroma – aired well the next day and it worked a treat

The instructions printed on the tub are misleading. According to three different test strips, and regular testing I have now learned to work out the amount of chlorine granules to add per 1000 Litres, which greatly differ from those provided on the tub. Buyer beware.

It’s that time of year our pools are opened up and heating is on and burning holes in our pockets, (and the rain keeping us away from having a dip). chemicals are over the top expensive, but this chlorine was delivered to my door within 48hrs and the product no different in anyway than my driving 12 miles to the closest pool chemical store and being ripped off for 30 quid.I am very pleased with the product, the price and the delivery time. This seller will be my monthly buy..
