HTH Mineralsoft Granular+ Chlorine 4kg

The HTH Mineralsoft Granular+ Chlorine 4kg is a high-performance, non-stabilised pool sanitiser formulated with calcium hypochlorite and silk-softening minerals. This dual-purpose granular treatment effectively eliminates bacteria and algae while preventing cyanuric acid build-up, ensuring water remains crystal clear and gentle on the skin for South African families during peak swimming seasons.

Ideal Use and Application

• • Sanitisation: Specifically designed for daily or every-second-day maintenance to maintain a free chlorine residual of 1–3 ppm.
• • Shock Treatment: Can be used at higher dosages to resolve algae blooms, cloudy water, or contaminants after heavy rainfall.
• • Rapid Dissolution: Engineered for fast action with minimal residue, helping to maintain immediate hygiene in residential and commercial pools.
• • Dosage Rate: Standard maintenance requires approximately 250g (one cup) per 50,000 litres of pool water.
• • Lining Compatibility: Suitable for all pool surfaces, including marbelite, vinyl, and fibreglass, when broadcast correctly.

Safety Precautions

• • Bleaching Prevention: For vinyl or coloured pool linings, add the granules directly into the weir while the pump is running to avoid surface staining.
• • Mixing Warning: Never mix this product with other pool chemicals, particularly stabilised chlorine or acids, as it can cause a violent chemical reaction.
• • Storage: Keep the 4kg container sealed in a dry, well-ventilated area away from direct sunlight and flammable materials.
• • Handling: Wear protective gloves and eyewear; in case of skin or eye contact, rinse immediately with fresh water for at least 15 minutes.

Frequently Asked Questions

• • Will this cause chlorine lock? No, as a non-stabilised chlorine, it does not contain cyanuric acid, which is the primary cause of over-stabilisation and chlorine lock.
• • What is the best time to apply this? Apply in the early evening to prevent the harsh sun from dissipating the active chlorine before it can sanitise the water.
• • When can I swim after use? You may safely re-enter the pool once the free chlorine levels have tested below 3 ppm.
• • Does it affect pH levels? Calcium hypochlorite has a high pH; always test and adjust your water balance weekly to maintain a pH of 7.2–7.6.

Local Pro-Tip

• • Add a half-dose of HTH Mineralsoft Granular+ Chlorine immediately after it rains; this neutralises organic matter before it has the chance to turn your water green.
