HTH Dry Acid is a safe, non-fuming granular solution for balancing pool water. By lowering pH and total alkalinity, it prevents cloudy water, stains, and irritation to eyes and skin. Its granular form is easier to handle than liquid acid and eliminates splashing risks, making it ideal for routine maintenance and maintaining effective chlorine levels.
To reduce pH, sprinkle granules around the pool while the filtration system is running. To lower total alkalinity, pre-dissolve the granules in a bucket of water before adding to the deep end, then run the filter for several hours and retest. For vinyl or coloured liners, pre-dissolving is recommended to avoid bleaching. Always wear gloves and eyewear and never mix with other chemicals.
Packaged in a 3 kg container, HTH Dry Acid is registered under Act 36 of 1947, providing a reliable and safe solution to keep pool water balanced and comfortable for swimming.
