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.

Going to last ages this one, 5kg though weighs a bit more of you count the container. Gives me awful heartburn though. Slightly gritty, but if you mix it with warm water it goes down so much easier. I’m getting so much cleaner inside and out now.

thought i would get a pot of the test strips but just a small sachet so not really much of a saving

It works fine but I do find you have to mix it on a separate bowl with hot water to dissolve it first before you put it in the hot tub. Otherwise you will fine the bits will stay in the bottom of the tub and it gets everywhere when the jet is on. Apart from that it does keep the water clear.Yes, I would put again even though it is a little expensive.

Arrived quickly just before I ran out of chlorine, this is the brand I always use as it is an excellent product. It keeps well and dissolves easily to add to the pool returning consistent results when dip tested.
