HTH is one of the world’s leading brands of dry chlorine because it is one of the safest and most economical methods of pool water treatment. With a lower pH than many other sanitisers, it can save upto 50% on pH correction costs. It provides a low level of Total Dissolved Solids (TDS) and therefore reduces plant corrosion. It contains much less salts than many alternative sanitisers – reducing the requirement, time and energy of costly water dilution. It is suitable for hard and soft water conditions and has added calcium to help prevent grout loss. The unique and patented “pillow shaped” briquette weighs 7gms and ensures great efficiency with minimal wastage. The briquette form offers an enhanced COSHH rating and has 70% available chlorine content.
