HTH Super Shock It Pool Treatment 600g

The HTH Super Shock It Pool Treatment 600g is an extra-strength, fast-dissolving non-stabilised chlorine sanitiser designed to rapidly superchlorinate pool water. This 600g booster treatment eliminates stubborn algae, bacteria, and organic contaminants, effectively restoring water clarity within 24 hours without contributing to cyanuric acid build-up or the risk of common pool chlorine lock.

Ideal Use and Application

• • Heavy-Duty Recovery: Formulated specifically for high-stress situations such as green algae outbreaks, heavy swimmer loads, or extreme South African summer heat.
• • Rapid Clarification: Acts as a powerful pool shock to transform dull, cloudy, or grey water into a sparkling blue state quickly.
• • Non-Stabilised Sanitiser: Contains high-purity calcium hypochlorite which provides an immediate "hit" of chlorine that dissipates naturally without leaving behind residual stabiliser.
• • Post-Rain Treatment: Excellent for neutralising nitrogen-rich contaminants and dust washed into the pool during Highveld thunderstorms or coastal wind events.
• • Dosage Requirement: One 600g bag is typically sufficient to shock treat a pool of up to 50,000 litres; always refer to current chlorine levels before application.

Safety Precautions

• • Chemical Compatibility: Never mix Super Shock It with other pool chemicals, especially floating dispensers or trichlor tablets, as this can cause a fire or explosion.
• • Protective Gear: Always wear gloves and eye protection when handling the pouch; avoid inhaling any dust when opening the package.
• • Correct Dissolution: To protect your pool lining, broadcast the granules into the deepest part of the pool or pre-dissolve in a bucket of water to prevent bleaching on marbelite or vinyl.
• • Storage: Store in a cool, dry place away from flammable materials, acids, and organic matter.

Frequently Asked Questions

• • How is "Super Shock It" different from the standard 500g "Shock It"? This 600g variant offers a higher concentration of active chlorine and a larger volume, making it more effective for larger pools or severe algae issues.
• • When is it safe to swim? Check the free chlorine level using a test kit; swimming should only resume once the reading is between 1 ppm and 3 ppm.
• • Will this affect my water balance? It has a high pH; while it is great for sanitisation, you may need to adjust your pH or Total Alkalinity following a heavy shock treatment.
• • Can I use this in a saltwater pool? Yes, it is a highly recommended "rescue" treatment for saltwater systems that are struggling to maintain chlorine levels during peak summer.

Local Pro-Tip

• • If you are planning a large weekend braai with many guests, "pre-shock" your pool with HTH Super Shock It the night before. By boosting the chlorine levels in advance, the water remains clear and sanitary even with a high number of swimmers, preventing that "milky" look that often appears the morning after a party.
