HTH Dry Acid 3kg

HTH Dry Acid 3kg is a concentrated granular chemical used to lower high pH and total alkalinity levels in swimming pool water.

This sodium bisulphate-based treatment serves as a safer, easier-to-manage alternative to liquid hydrochloric acid, effectively preventing scale formation on pool surfaces and ensuring that chlorine sanitisers operate at their peak disinfection potential.

Product Specifications and Features

• • Granular Sodium Bisulphate formula provides a high-purity acidic agent that dissolves rapidly in water without the dangerous fumes or splashing associated with liquid acids.
• • pH Reduction Capability allows for precise control of water balance, moving the pool environment toward the ideal range of seven point two to seven point six.
• • Alkalinity Management helps reduce total alkalinity levels when they exceed one hundred and twenty parts per million, preventing cloudy water and mineral deposits.
• • Corrosion and Scale Prevention ensures that high pH levels do not cause calcium to precipitate and form rough white scales on pool tiles, salt cells, or heaters.

Ideal Use and Application

• • High pH Correction is necessary when swimmer waste, chemical imbalances, or source water causes the pool to become too alkaline, leading to itchy eyes and skin.
• • Salt Water Chlorinator Maintenance is a primary use case, as salt systems naturally tend to drive pH levels upward, requiring regular acid additions to protect the electrode plates.
• • Surface Cleaning applications include using a concentrated solution to treat localized calcium stains on marbelite or concrete finishes.

Safety and Handling Precautions

• • Pre-Dissolving Requirement dictates that granules should be added to a plastic bucket of water, never the other way around, and stirred with a wooden or plastic tool.
• • Gradual Addition is essential; add the dissolved solution to the deep end of the pool while the pump is running and wait at least four hours before re-testing.
• • Safe Storage involves keeping the three kilogram container in a dry, well-ventilated space, ensuring the lid is tightly closed to avoid moisture absorption and clumping.
• • Protective Equipment including rubber gloves and eye protection should be worn to avoid chemical burns or irritation during the mixing process.

Frequently Asked Questions

• • Is dry acid better than liquid acid? Both achieve the same result, but dry acid is significantly easier to transport in a vehicle and eliminates the risk of acid spills or corrosive fumes in your storage shed.
• • How much should I use? Dosage depends on your current pH and pool volume; generally, two hundred and fifty grams will lower the pH of a fifty thousand litre pool by approximately zero point two units.
• • Can I swim after adding it? It is recommended to wait at least one to two hours to allow the acid to disperse and the water to reach a uniform balance.

Maintenance Tip

• • To keep your pool tiles looking new in areas with hard water, keep an old spray bottle filled with a weak solution of HTH Dry Acid and water.
• • Spraying this directly onto the white calcium "waterline" marks on your tiles and scrubbing gently with a soft brush during your weekly maintenance prevents the scale from hardening, saving you from a much more difficult and expensive deep-clean later in the season.
