Description
These chlorine tablets are one of the most popular products for ensuring hot tub and swimming pool water is safe and bacteria free. They are stabilised to minimise chlorine loss to sunlight. They slowly release chlorine over 2–4 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 hot tub or 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 hot tubs between 3-5mg/l and for swimming pools between 1 – 3mg/l (ppm). Freshly filled hot tubs 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 3-5mg/l (ppm) desired range. Alternatively keep the dispenser aperture constant and vary the tablets inside to achieve 3-5mg/l (ppm). The dispenser should be removed from the hot tub whilst bathing.
4. For chlorine feeders: Fill the dispenser and follow feeder instruction manuals on flow regulation to maintain required chlorine levels.
5. For skimmer baskets: Fill the basket with sufficient tablets and monitor levels to maintain required 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)
Medium hot tub 1,000 litre (220 Gallons) of water requires approx 1 tablet to increase the chlorine level by 1mg/l (ppm) or 3 tablets to increase chlorine level by 3mg/l(ppm)
Large hot tub 1,500 litre (330 Gallons) of water requires approx 2 tablets to increase the chlorine level by 1mg/l (ppm) or 6 tablets to increase chlorine level by 3mg/l(ppm)
Swimming pools add 1 tablet per 4,500 litres (1000 Gallons) of water and monitor levels.

Maybe just our bad luck but we’ve had a tablet in a floater for quite a few days now and hasn’t dissolved.

It works really well. Add to dispenser, drop into pool. Leave and take out before you or your children go in the water. Deep blue, doesn’t do anything about the temperature of water though Ha ha ha!

Using these in a hot tub it has been some whilesince I last made a purchase havlng used bromine previously due to a previous economial large tub purchase. Ok, glad to be back with chlorine and this product was well packed, with a hard to open lid that would have deterred the most determinedchild and possibly most adults the lid was finally removed. No loose tablets here they were contained within a sealed bag inside the plastic tub. Now nI’m not sure if this was an additional level of security or just another measure to keep the product fresh but once the bag was open the strong pungent smell of chlorine was unavoidable. This product was so fresh it was unbelievable and when added to my hot tub in the measured amount the differenc was undeniable, once again the water smelt and felt fresh and a feeling of protection and germ killing was once more evidend. So much better than bromine, much more control able and the water appears brighter, with the particular freshnessof this seller I beleive this is possibly chlorine a its best. Fantastic fresh product, cation should be taken when using this product not to inhale fumes, keep in a dry environment and never handle this product without gloves outside and not in enclosed space. Treat this product as you would bleach or any othrer dangerous product and keep away from children.
