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.

Chlorine tablets that you can put into floating dispensers in spas or pools.Easy to use, no dose measures to get wrong. Place tablet in dispenser, if chlorine is needed, will take it from the tablet.

I’ve been trying to use Chlorine tablets in my lazy spa for sometime and i’ve decided to switch back to the granules after several weeks of no success with these. Why is this you may ask? Well if you asked a handful of people how much salt they like on their popcorn or how they like their steak cooked most people would have a different answer. You make it to order! Now imagine the same situation but you only had 1 product.. rare steak and heavy salted popcorn, it wouldn’t work and this is the issue with the chlorine tablets. Your trying to guess the demands of your lazy spa using a pre made product. With the chlorine granules you take a dip test and depending on the colour you know how many grams to add to the water. With the tablets while you can adjust the floating dispenser by opening the little flaps to limit how much chlorine is released; the time in which this takes is much greater then the granules and you don’t really know how much is being released, i.e a new tablet compared to a 3 day old tablet is different in size and the amount its releasing. If your not too fused about keeping your lazy spa on the nose then yeah shove one of these in every 3 or 4 days but if you want your lazy spa fine tuned get the granules.

Really easy to use, cleared our 8ft pool of algae quickly and the water has remained clear the rest of the summer and doesn’t overly smell of chemicals
