Happy Stabilised Chlorine Granules (55%) are used for the disinfection of hot tub, swimming pool and paddling pool water.
- High quality, fine granules
- 55% concentration
- Rapid dissolving
- Designed for minimal affect on pH level
- Ideal for daily dosing
- Stabilised to protect against chlorine loss due to sunlight
- Great for hot tubs, splashers or swimming pools
- Maintain a Free Chlorine residual of betweem 2 and 3ppm (parts per million) for pools and 3-5ppm for hot tubs.
- For pools, pre-dissolve granules in a clean plastic bucket filled with pool water.
- For hot tubs, add directly to the water.
- To increase the chlorine residual in 1000 litres of water by 1ppm, add 2g of Chlorine Granules. (e.g. 140g of Chlorine Granules added to 70,000 litres of water will increase the chlorine residual by 1ppm). One heaped teaspoon holds apporximately 7g of chlorine granules.
- Ensure that the hot tub or pool circulation pump is running when adding the product. Operate circulation pump for at least 30 minutes after adding the product to allow it to disperse.
- Re-test the water to ensure the optimum chlorine level is achieved (Pools - 2 to 3ppm, Hot tubs 3-5ppm)
- Never add product when pool or spa is being used. Do not allow pool or spa to be used for at least 30 minutes after dosing.
