Description
These chlorine granules are one of the most popular products for ensuring pool and spa water is safe and bacteria free.
Apply regularly to achieve the recommended free chlorine level of 3-5 mg/l (ppm) for hot tubs or 1-3 mg/l (ppm) for swimming pools. 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.

Great for hot tub

Good chlorine mixture and does exactly what it says on the tub. A little does go a long way and if used correctly doesn’t result in a strong chlorine scent.

Needed chlorine during lock down and normal supplier was closed, this product has done what it needed to do, however water appeared to go slightly cloudy and the chlorine didn’t last as long as I expected so needed topping up fairly often even when not using it, even when water was cloudy the water levels were safe to use, the chlorine just appeared to wear off quicker than other brands I have used

not good for my inflatable spa they dont dissolve properly leavin bits at bottom of spa and they dont release the correct dosage I was recommended 2tabs in dispenser every 3days this gave an initial sky high reading then readng the next eve was less than one ppm spa reading should be 3-5ppm my advice would be to stick to the granules
