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.
Dose Rates
Medium hot tub 1,000 litre (220 Gallons) of water requires 2g to increase the chlorine level by 1mg/l (ppm) or 6g to increase chlorine level by 3mg/l(ppm)
Large hot tub 1,500 litre (330 Gallons) of water requires 3g to increase the chlorine level by 1mg/l (ppm) or 9g to increase chlorine level by 3mg/l(ppm)
Small pool 40,000 litres of water requires 80g to increase the chlorine level by 1mg/l (ppm) or 240g to increase chlorine level by 3mg/l(ppm)
Medium pool 60,000 litres of water requires 120g to increase the chlorine level by 1mg/l (ppm) or 360g to increase chlorine level by 3mg/l(ppm)
Large pool 80,000 litres of water requires 160g to increase the chlorine level by 1mg/l (ppm) or 480g to increase chlorine level by 3mg/l(ppm)

Great Product & Quick Delivery

Been using this ‘stabilized’ chlorine product for a long time now, and for the price £9.99 and free delivery it is one of the best price places to buy this.We use a 10ft bestway outdoor fast set pool, and this stuff keeps the water crystal clear, and 100% algae free. I use about 20g to keep the pool around 4 to 5 ppm / mg/l (parts per million, or milligrams per litre). This is at the upper limit of the manufacturers guide, but they’re being too cautious – I come from a family of lab chemists, and vouch that at these levels it’s safer to drink a litre of the chlorinated pool water than a litre of some of the soft drinks out there! 🙂 Think for a moment that in some dermatology practices, people immerse themselves in waters with concentrations of chlorine starting at 50 PPM.. (that’s literally 10 times more than we cautiously trickle into our pools) don’t worry.. you’re not going to melt or find yourselves rushing to the hospital if you go a bit over, so never panic. Remember it is ALWAYS safer to swim in slightly over chlorinated water, than unsanitised, under chlorinated water. —– 5ppm works perfectly for us. FYI, stabilized chlorine has an acidic stabilizing agent to prevent the chlorine vanishing in a puff of vapor. Stabilizing chlorine prolongs the life of chlorine in the water, but a side effect is that it raises the acidity level in the water ever so slightly.. only when acidity reaches higher than wanted levels is when you need to help the water out a bit… my advice… Chuck some sodium bicarbonate (baking soda / bicarbonate of soda) in if ph is showing a bit too low on your test sticks, no need for expensive additives. Usually, most test strips have steps (i.e. one colour band to the next). Our pool is just shy of 4000 litres and I find approx 65g of bicarb brings the acidity down one step. Far cheaper than the branded PH increasers (£5 per kilo vs £10).There’s no need to rate less than 5 stars unless you’re judging the price. This stuff works, does exactly what it’s supposed to. At £10, great value. Homebase sells this for £15. The chlorine itself is spot on, and contaminate free.

Anticipated the granules to be a bit bigger to go in a dispenser, otherwise, works well.
