hth Calcium Hypochlorite manufactured by Sigura, is one of the world’s leading brands of dry chlorine. Increasingly many pool operators are changing to hth calcium hypochlorite because it is one of the safest and most economical methods of pool water treatment.

The sheer convenience of hth calcium hypochlorite and the absence of bulk storage tanks is one reason for its rapid growth in popularity - hth can use fewer chemicals for pH correction and waste less water for Total dissolved Solids (TDS) control than many other sanitisers.

• hth dry chlorine products are available in a choice of granular or briquette form and with standard or Easiflo® options, all in a variety of pack sizes to suit any pool.
• With a lower pH than many other sanitisers, hth can achieve a saving of up to 50% on pH correction costs
• hth provides a low level of Total Dissolved Solids (TDS) and therefore reduces plant corrosion
• hth contains much less salts than many alternative sanitisers - reducing the requirement, time and energy of costly water dilution
• hth is suitable for hard and soft water conditions and has added calcium to help prevent grout loss
