Product Specifications and Benefits

• • Dual Action System includes a concentrated chlorine shock to neutralise organic contaminants and a secondary booster to enhance water clarity and brightness.
• • Rapid Dissolution Technology ensures the chemicals begin working immediately upon contact with the water, effectively treating green and black algae blooms.
• • Non-Stabilised Formula allows for heavy shock dosing without increasing cyanuric acid levels, helping to avoid the common issue of chlorine lock.
• • Pre-Measured Packaging provides the exact dosage required for a fifty thousand litre pool, eliminating the need for complex measuring or chemical handling.

Ideal Use and Application

• • Emergency Recovery is recommended for pools that have turned green due to power outages, pump failure, or extreme heat during the South African summer.
• • Application Method requires ensuring the pump is running on the filter setting and adding the granules directly into the weir for even distribution.
• • Water Balance Preparation is critical; for best results, ensure the pH is adjusted to between seven point two and seven point six before starting the treatment.

Safety and Storage Precautions

• • Avoid Mixing Chemicals as this product is a strong oxidiser and can react violently if it comes into contact with acids or other chlorine types.
• • Protective Measures suggest wearing gloves and eye protection when pouring the granules and avoiding application during high wind to prevent inhalation.
• • Storage Instructions dictate keeping the container upright in a cool, dry, and well-ventilated storeroom away from direct sunlight and flammable materials.

Frequently Asked Questions

• • How long does the transformation take? Most pools will see a visible change from green to cloudy blue within twenty-four hours, though final filtration may take longer.
• • Do I need to vacuum after use? Yes, once the product has settled the dead algae to the floor, manual vacuuming to waste is necessary to remove the sediment permanently.
• • Can I use this in a vinyl pool? Yes, this product is compatible with vinyl, fibreglass, and plaster linings, provided it is added through the weir to prevent bleaching.
