    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.

It dispenses the chlorine into the top layer of pool water where bacteria and dirt concentrations are at their greatest to kill bacteria and algae spores before they have a chance to develop. the Easyclic Mini Chlorine Dispenser can be used as an additional chlorine "top-up" with other HTH chlorine sanitisers, on its own in above ground pools during the summer Holiday period, or even for lengths of time when the pool is not in use if you are away on holiday.

        RETURNS: HTH 5 EASYCLIC Floating Chlorine Dispenser can be returned unused, in original packaging, suitable for resale, within 14 days from date of delivery.

        PRODUCT INFO:

        HTH EASYCLIC provides a constant supply of residual chlorination for up to 6 weeks. HTH easyclic chlorine dispenser works its magic in the first 10-15 centimetres of swimming pool water, the most polluted level of a swimming pool, to reduce the risk of bacterial and algal infection. The HTH easyclic dispenser contains 1.66kg of Multifunctional Chlorine Tablets which will dissolve slowly over a period of time.

        The HTH 5 Buoy can be used as an additional sanitiser in conjunction with other HTH chlorine sanitisers, on its own, normally in above ground swimming pools during the Summer holidays, or for extended periods when the pool is not in use and the filtration is not running, such as when you are on holiday.

        Instructions For Use: Adjust pH to 7.2-7.6 with HTH pH reducer or HTH pH increaser as appropriate. At the start of the swimming season use Shock & Sanitiser when opening the pool.

        Remove the plastic label, setting the HTH easyclic dispenser to the correct pool volume as described on the label. Keep the label for future reference and safety information. Twist the blue cap of the 5-Buoy to choose the correct hole size for the volume of your swimming pool, if you need help working this out use this link to our Swimming Pool Chemical Handbook to use the handy swimming pool volume calculator. Place the HTH 5-Buoy dispenser in the deepest part of the swimming pool with the blue cap on the surface of the water. Hold it partly under water until the air has been removed and ensure there is free water flow through the cartridge. Never fully submerge the blue buoyancy section. Ensure the HTH 5-Buoy dispenser is floating vertically. If you have a liner pool it is advisable to keep the buoy from sitting in one place on the sides to avoid bleaching the liner.

        If no other chlorine has been used allow 3-4 hours before bathing to allow residual chlorine level to rise.

        Try to maintain the free chlorine residual level between 2-4 ppm.

        When children or any bathers are in the pool take the HTH 5 Buoy Floating Chlorine dispenser out of the pool and place in a bucket of pool water. When the bathers have finished in the pool pour the water and buoy from the bucket back into the pool.

        The HTH 5 easyclic will float on its side when it is empty. At this time replace the old one with a new -Buoy Chlorine Dispenser.

          PRODUCT INFO:

          HTH pH Minus Micro-Balls 5kg comes in a 5kg container. Depending on the how it is used to dose your swimming pool or hot tub, HTH pH Minus Micro-Balls 5kg will lower either the pH or the Total Alkalinity in the water. High pH will cause cloudy water and can be a factor in scale formation. High pH may also reduce the sanitisation effectiveness of chlorine. Swimming Pool & Hot Tub water with a high alkalinity reading will be difficult to lower the pH as any chemicals designed to lower pH will automatically will be used up by the buffering action of the alkalinity.

          Instructions To Correct High pH Levels in Swimming Pools or Hot Tubs using HTH pH Minus Micro-Balls 5kg

          Test your pool water using your prefered testing method. If higher than 7.6 you will need to lower it

          With the pumps and filtration running, sprinkle the amount suggested on the label of HTH pH Minus Micro-Balls 5kg evenly around the pool, avoiding the skimmer areas. Do not dose more than 500g at any one time. If more than 500g is required repeat the process after 24 hours.

          Leave the filtration running and re-check the pH levels after 24 hours. If required redose with HTH pH Minus Micro-Balls 5kg

          Instructions To Correct High Alkalinity Levels in Swimming Pools or Hot Tubs using HTH pH Minus Micro-Balls 5kg

          Calculate your pool water volume, if in doubt call us and we can advise you.

          Test your pool water using your preferred testing method. If the Total Alkalinity reading is higher than 150 mg/l (ppm) you will need to lower it.

          With the Pump & Filtration OFF pour 1kg, in 200g increments, into one area at the deepest end of the pool, away from the skimmers. Each 1 kg dose should reduce the Alkalinity levels by 10-20 mg/l  (ppm)

          After 24 hours re-test the swimming pool or hot tub and if the Total Alkalinity reading is still above 150 ppm then repeat the dose until the level is correct.
