Description
These chlorine tablets are one of the most popular products for ensuring swimming pool water is safe and bacteria free. They are stabilised to minimise chlorine loss to sunlight. They slowly release chlorine over 3–5 days depending on the water flowing over them.
They can be used in floating dispensers, chemical feeds and skimmer baskets.
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 tablets are slow release and long lasting and have the minimum effect on the pH of the water for a stabilised chlorine tablet.
Key Features
Its best to operate a free Chlorine Range of 3 – 5mg/l for hot tubs and 1-3mg/l for swimming pools. These stabilised chlorine tablets are ideal for regular dosing of your swimming pool, to produce free active chlorine which kills bacteria and other potentially harmful organisms. They contain a high level of available chlorine and chlorine stabiliser.
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 swimming pools between 1 – 3mg/l (ppm). Freshly filled pools require an initial shock or start up dose of chlorine: 50mg/l (ppm) for 1 hour or 20mg/l (ppm) for 2 hours.
3. For floating dispenser: Fill the floating dispenser with tablets and adjust the aperture mechanism at the bottom of the dispenser to obtain the 1-3mg/l (ppm) desired range. Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 1-3mg/l (ppm). The dispenser should be removed from the pool whilst swimmers are bathing.
4. For chlorine feeders: Fill the dispenser and follow feeder instruction manuals on flow regulation to maintain 1-3 mg/l (ppm) chlorine levels.
5. For skimmer baskets: Fill the basket with 2/3 tablets and monitor levels to maintain 1-3 mg/l (ppm) chlorine levels.
6. It is recommended that you periodically (e.g. fortnightly or after heavy use) shock dose your pool to eliminate any excess contamination.
Note: If using in skimmer baskets we would suggest you run the pump often to prevent a build up of chlorine. Please ensure children to not have access to the skimmer as this could be dangerous.
Dose Rates (subject to water flow rate and temperature)
Small pool 40,000 litres of water requires approx 1 tablet to increase the chlorine level by 1mg/l (ppm) or approx 3 tablets to increase chlorine level by 3mg/l(ppm)
Large pool 80,000 litres of water requires approx 2 tablets to increase the chlorine level by 1mg/l (ppm) or approx 6 tablets to increase chlorine level by 3mg/l(ppm)

great tablets for swimming pool would recommend

I brought these Chlorine tablets for my Canadian Spa. I normally use the liquid. But I ran out of it so I brought this instead. You need to put the tablet(s) in a floater otherwise they sink to the bottom. And is way to contrated. If you buy these for your Spa/ Hot Tub buy a floater just beware if you have young children these might not be suitable as children can always touch or play with the floater. I highly recommend you getting the Chlorine liquid. If you want to be sure your Spa/ Hot Tub is safe to use within a hour.

Kept our 8ft bestway pool clean for the 6 weeks we sort of had some sun in north east 2014, pool smelt clean and stayed clean great product

bought this unbranded chlorine tablet because they were £7 cheaper than DeepBlue but they simply don’t work. I was using 3 tablets in a floater with the branded product but with this I am using 8 (the most I can put in the floater) and it still does not register when using a PH stick. Use something else, these do not work

I would not buy these again. I don’t know if I have a dodgy batch but they are not putting any chemical balance into my water. Total waste of money.

This product contains an anti-flocculant as well as the chlorine. Small debris clumps together and somehow gets taken out by the filter more effectively. It helped keep our water even cleaner than when we used to use just granules.
