BLU52 Clear Shock Pool Treatment 500g

The BLU52 Clear Shock Pool Treatment 500g is a concentrated oxidising sanitiser engineered for the rapid elimination of organic contaminants, chloramines, and algae. This fast-dissolving calcium hypochlorite formula restores crystal clarity to swimming pool water without affecting the pH balance, providing an efficient chemical boost for residential pools following heavy rain or high swimmer loads.

Ideal Use and Application

• • Rapid Oxidisation: Formulated to quickly break down body oils, cosmetic residues, and organic waste that cause dull or hazy water.
• • Algae Control: Effectively kills active algae spores and prevents future growth when used as part of a weekly maintenance routine.
• • Surface Compatibility: Safe for use in all pool types, including concrete, marbelite, fibreglass, and vinyl linings, as it dissolves quickly without leaving residues.
• • Measured Dosing: The unique re-sealable ziplock bag allows for precise application, making it ideal for smaller pools or targeted "spot" treatments.
• • Sanitation Boost: Restores chlorine efficiency by removing the "used" chlorine (chloramines) that causes typical chemical odours and eye irritation.

Safety Precautions

• • Storage and Handling: Always keep the ziplock bag tightly sealed when not in use and store in a cool, dry area away from heat sources or flammable liquids.
• • Avoid Mixing: Never mix this product with other chemicals, especially stabilised chlorine tablets or acids, as this may result in a hazardous chemical reaction.
• • Personal Protection: Use protective gloves and eyewear during application; avoid breathing in dust or allowing the product to contact skin for extended periods.
• • Direct Application: Do not allow undissolved granules to sit on the pool floor, as this may cause bleaching; broadcast evenly across the surface while the pump is running.

Frequently Asked Questions

• • Does this product contain stabiliser? No, BLU52 Clear Shock is a non-stabilised treatment, meaning it will not raise your cyanuric acid levels or contribute to chlorine lock.
• • How long must I wait to swim? Swimming can typically resume once the water is clear and free chlorine levels have returned to a safe range of 1–3 ppm.
• • Can this be used with the BLU52 All-In-One system? Yes, it is perfectly compatible and recommended as an additional "shock" treatment if the water balance is compromised.
• • Will it change my pH? This formula is specifically designed to be pH neutral, meaning you won't need to add corrective acids or alkalis after shocking.

Local Pro-Tip

• • Use this product specifically for your weekly shock; its fast-dissolving nature helps prevent the calcium scaling that often occurs with slower-reacting granules, keeping your pool tiles looking cleaner for longer.
