Each 5-Buoy dispenser contains 1.66kg of Multifunctional Chlorine

    Place the 5-Buoy in the deep end of the pool with narrow end downwards. Hold it partly immersed to exclude air, and ensure there is free water flow through the cartridge. Never submerge the blue buoyancy compartment.

    Make sure the 5Buoy is floating vertically. With liner pools keep away from sides to avoid bleaching. 

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

        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:

            HTH Clarishock is the new name for Fi-Clor Rapid Clarifier and is an ultra concentrated liquid specifically designed to give the best pool water clarity on swimming pool, with sand or glass filters, when compared with other Brands of swimming pool clarifiers.

            Following the directions, and dosing with the simple to use measuring cap, will return your pool water to crystal clear and keep it like that if used regularly.

            HTH Clarishock works both as a clarifier and flocculant. Fine particles suspended in your swimming pool water that cannot be retained by the filter, make the water cloudy. HTH Clarishock helps particle aggregation, the process by which suspended colloids clump together and are either collected in the sand filter, to be backwashed out later, or come out of suspension as a floc which then collect at the bottom of the pool as debris to be vacuumed to waste.

            Instructions To Clear Cloudy Water in Swimming Pools using HTH Clarishock Rapid Clarifier

            Calculate your swimming pool water volume, if in doubt call us and we can advise you. Check pool water balance and ensure Chlorine level is between 1-3ppm & pH level 7.2 - 7.6

            Restoring Cloudy Water To Crystal Clear: Dose rate of HTH Clarishock Clarifier: 100ml Per 50m3 (50,000 litres / 11,000 UK Gallons). In order for HTH Clarishock to work your filtration must be running. If debris collects on pool floor, vacuum to waste. Regularly check filter pressure and backwash if required. If pool is still cloudy after 24 hours backwash and repeat dose.

            Preventing Cloudy Pool Water: Dose rate of HTH Clarishock Clarifier: 100ml Per 50m3 (50,000 litres / 11,000 UK Gallons) once a week.
