BLU52 Hi-Strength Pool Acid 5L

BLU52 Hi-Strength Pool Acid 5L is a concentrated 30% hydrochloric acid solution formulated to regulate water chemistry by reducing high pH and total alkalinity levels. This professional-grade liquid treatment prevents calcium scaling and cloudy water while significantly increasing the sanitising power of chlorine, ensuring a safe and balanced swimming environment for South African residential and commercial pools.

Ideal Use and Application

• • pH Regulation: Specifically used to lower pH levels when they exceed the ideal range of 7.2 to 7.6, preventing skin and eye irritation.
• • Alkalinity Adjustment: Acts as a powerful agent to reduce high total alkalinity, which helps prevent pH "bounce" and scale formation on pool surfaces.
• • Scale Removal: Effective at dissolving calcium deposits and mineral build-up on pool tiles, salt chlorinator cells, and heating equipment.
• • Anti-Glug Design: The 5-litre container features a specialised anti-glug pour spout to ensure a steady, splash-free flow during application.
• • Sanitiser Optimisation: By maintaining the correct acid balance, this product ensures that pool chlorine remains in its most active, bacteria-killing state.

Safety Precautions

• • Protective Equipment: Always wear acid-resistant gloves, safety goggles, and closed-toe shoes when handling or pouring this high-strength corrosive liquid.
• • Dilution Protocol: Never add water to acid; always add the required dose of acid into a bucket already filled with pool water to prevent dangerous splashing or thermal reactions.
• • Storage Safety: Store the bottle upright in a cool, well-ventilated area away from children, pets, and reactive chemicals like chlorine or soda ash.
• • Childproof Cap: Ensure the childproof lid is clicked firmly into place after every use to prevent accidental exposure or leaks.

Frequently Asked Questions

• • Can I pour the acid directly into the pool? No, it must be pre-diluted in a bucket of water and distributed evenly around the perimeter while the pump is running to avoid damaging the pool lining.
• • How soon can I swim after adding acid? It is recommended to wait at least 3 to 4 hours with the filter running to ensure the acid is fully dispersed and the pH has stabilised.
• • What happens if my pH is too high? High pH makes chlorine up to 80% less effective, leading to algae growth and cloudy water despite having enough sanitiser present.
• • Does this product expire? Hydrochloric acid is highly stable and does not "expire," but the plastic container can degrade over several years if stored in direct sunlight.

Local Pro-Tip

• • For a sparkling finish on your patio, a highly diluted mixture of BLU52 Hi-Strength Pool Acid and water is a "go-to" for cleaning stubborn cement stains or efflorescence (white salt marks) off new brickwork or paving stones; just be sure to rinse the area thoroughly with a hose immediately after scrubbing to protect the grout.
