HTH Clear 4 Weeks Shock Clarifier 500g

HTH Clear 4-Weeks Shock Clarifier 500g is a specialised, non-stabilised chlorine treatment that combines a high-strength sanitiser with a long-acting flocculant. This unique granular formula oxidises organic contaminants while clumping fine debris together, allowing your filter to remove them more effectively and maintaining water brilliance for a full month in South African residential swimming pools.

Ideal Use and Application

• • Water Restoration: Specifically engineered to clear cloudy or hazy water by gathering suspended microscopic particles that standard filters might otherwise miss.
• • Monthly Clarification: Provides a sustained clarifying effect that lasts up to four weeks, reducing the frequency of maintenance chemical additions.
• • Oxidising Power: Effectively eliminates organic contaminants, bacteria, and algae spores to restore a hygienic swimming environment.
• • Compatibility: Suitable for use in all pool types, including marbelite, vinyl, and fibreglass, when broadcast correctly.
• • Dosing Requirement: One 500g pouch is designed to treat a standard pool of up to 50,000 litres for a single deep-cleansing shock application.

Safety Precautions

• • Chemical Handling: Do not mix this product with any other pool chemicals, especially acids or stabilised chlorine, as this can lead to a fire or the release of toxic gas.
• • Application Time: For best results and to prevent the sun's UV rays from dissipating the chlorine, always apply the shock treatment in the evening.
• • Corrosion Warning: This is a strong bleaching agent; ensure granules are fully dissolved and do not settle on the floor to prevent staining or corrosion of metal fixtures.
• • Swimming Gap: Do not enter the pool until the free chlorine residual has dropped below 3 ppm as per test kit results.

Frequently Asked Questions

• • Can I use this instead of my normal chlorine? No, this is a supplementary shock treatment; you should continue with your regular sanitisation routine (such as floaters or granules) after the shock process.
• • How long should I run my filter after application? For the clarifying agents to work effectively, you must run your pool pump on the "Filter" setting for at least 24 hours post-treatment.
• • Will it cause chlorine lock? Since this is a non-stabilised calcium hypochlorite formula, it does not add cyanuric acid to the water and will not contribute to chlorine lock.
• • Does it affect pH? This product can slightly raise pH levels; it is recommended to check and correct your pH balance 12 hours after application.

Local Pro-Tip

• • Use this 4-week shock treatment specifically before backwashing. The clarifier will help trap fine dust in the sand filter, allowing you to flush out all the trapped debris in one go, saving you both water and time on repeat vacuuming.
