    PRODUCT INFO: HTH Supercapsules come in a 4.5kg container. HTH Supersapsules can be used as pool sanitiser. Supcapsules are recommended for pools that are open all year round. The HTH Supercapsule tablets are enclosed in a plastic sleeve making them easy to handle. Chlorine is slowly released as the capsule dissolves, from either end of the sleeve. The surface area of the capsule exposed to water remains constant so, unlike standard 200g tablets, your pool water has an even amount of chlorine going into the pool from start to finish with no chlorine lock

  • HTH SUPERCAPSULES SHOULD BE PLACED IN THE SKIMMER BASKET ONLY. NEVER USE THE CAPSULES IN FEEDERS OR AUTOMATIC CHLORINATORS.
  • Do not remove the sleeve. Once all the chemical has dissolved, the plastic sleeve will float and the sleeve can then be removed from the skimmer and discarded.

          PRODUCT INFO:

          Relax 5kg Stabilised Large Chlorine Tablets (Sodium Dichloroiscyanurate-Dihydrate) are the most simple and effective choice for your swimming pool. Being virtually pH neutral it is possible to dose your swimming pool with Chlorine throughout the summer without affecting the swimming pool water pH by any noticeable degree. If you have an indoor pool, we would suggest using Un-stabilised Chlorine, commonly called Shock.

          The ideal chlorine reading in your pool water is between 1 and 3 ppm, this figure can easily tested using Aquachek Test Strips. Testing your pool water daily will allow you to keep control of the swimming pool chlorine level very easily. If the reading is too low, you will simply need to add more Chlorine Granules to the pool water. Full instructions, measurements and quantities are provided on each tub.

          Little and often is the most effective method of dosing your swimming pool with Chlorine, as it is a lot easier to correct under dosing than it is over dosing.

          The impact of pH on efficiency of Chlorine in your Swimming Pool

          Your Swimming Pool pH value has a direct impact on the ability of the Chlorine to sanitise swimming pool water efficiently. A high pH level generally means Chlorine Granules are less efficient.
          Water pH of 6.5 - Chlorine in your pool is around 90% efficient
          Water pH of 7.0 - Chlorine in your pool is around 75% efficient.
          Water pH of 7.5 - Chlorine in your pool is around 47% efficient
          Water pH of 8.0 - Chlorine in your pool is around 22% efficient.

          PRODUCT INFO:

          Clear and Safe Chlorine tablets are used for the sanitisation of your pool, spa or hot tub, it's an essential chemical to keep the water, you and your family CLEAR & SAFE™ from harmful bacteria and germs that naturally occur in untreated water. This product provides a stabilised sanitisation that kills bacteria and viruses.

          Water in pools and spas should be tested daily, you are aiming to achieve a pH level reading between 7.2 and 7.6 before adding the chlorine. Use pH+ or pH- to adjust if necessary. Pool free chlorine levels must be between 1ppm* and 3ppm* and spas should be between 3ppm* and 5ppm*. Maintain these levels to keep your water CLEAR & SAFE™.

          These are high strength slow dissolving tablets, they take 2-3 days to dissolve in a hot tub and 3-5 days in a colder swimming pool.

The dissolution rate also depends on how they are being dosed, high water flow around the tablet will be quicker than in a floating dispenser.
