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.

Ruined a perfectly good night in the hot tub. My sister, who has sensitive skin, noticed she was itching, and we (others in the tub) soon followed, we wondered if we were being placebo-paranoid, but there was a definite prickly feeling, and the smell was so strong. Our eyes were stinging by the time we got out. Now, it is important to note that I changed NOTHING of my usual Hot Tub treatment routine. Just the granules.

Great value bulk buy which is much cheaper than buying branded chemicals for my inflatable hot tub. It is obviously a large and bulky item so I kept my old smaller tub to transfer to make it easier, but any old tub you have you could do the same and it is worth it for the better price bulk amount. Highly recommended.
