Product Overview

Sodium Bisulphate 25kg Bag (Dry Acid / pH Minus) is a high-quality, technical-grade product designed to effectively reduce pH and total alkalinity in swimming pools and spas. Composed of sodium hydrogen sulphate (NaHSO4), this odorless, white granular powder offers a safer and more convenient alternative to liquid muriatic acid. By maintaining the ideal pH range of 7.2–7.6 (or up to 7.8 for bromine-treated systems), it prevents scaling, cloudy water, and irritation, ensuring optimal water chemistry for both residential and commercial applications.

Key Features

• Effective pH and Alkalinity Reduction: Quickly lowers high pH and total alkalinity to the optimal range, preventing water quality issues and equipment damage.

• Safer Handling: Granular form reduces the risks associated with liquid acids, making it easier to store, transport, and apply.

• High Potency Formula: Technical-grade sodium bisulphate ensures efficient results with minimal product usage, maximizing value.

• Universal Compatibility: Suitable for all pool types (in-ground, above-ground) and spas, regardless of surface finish or sanitizing system (chlorine, bromine, or saltwater).

• Generous 25kg Size: Provides a long-lasting supply for multiple treatments, ideal for frequent or large-scale pool maintenance.

• Eco-Friendly Packaging: Packaged in a durable, industry-standard bag designed to minimize waste and ensure safe storage.

Benefits

• Crystal-Clear Water: Maintains balanced pH levels to prevent cloudy water and scaling, delivering a sparkling, inviting pool or spa.

• Enhanced Swimmer Comfort: Reduces eye and skin irritation caused by high pH, ensuring a refreshing and enjoyable swim.

• Protects Pool Equipment: Prevents corrosion and scale buildup on pumps, heaters, filters, and other components, extending equipment lifespan.

• Cost-Effective Maintenance: Stabilizes water chemistry, reducing the need for additional chemical treatments and saving on long-term costs.

• User-Friendly: Easy-to-measure granular form simplifies application, making pool maintenance hassle-free for both homeowners and professionals.

Usage Instructions

1. Test Water Chemistry: Use a reliable pool test kit to measure pH and total alkalinity. The ideal pH range is 7.2–7.6 (or up to 7.8 for bromine-treated systems).

2. Dosage Guidelines:

   • Pools: Add 450–500 grams of Sodium Bisulphate per 10,000 gallons of water to lower pH by approximately 0.2 units. For hard water, use up to 900 grams; for soft water, use 225–250 grams.

   • Spas: Add 10–15 grams per 1,000 liters of water to lower pH by approximately 0.2 units.

3. Application Steps:

   • Pre-dissolve the required amount in a clean plastic bucket filled with warm water (100g per 10 liters of water) and stir until fully dissolved.

   • Ensure the pool or spa circulation system is running and no bathers are present.

   • Slowly pour the solution near the water return inlets to ensure even distribution.

   • Rinse the bucket thoroughly after use to prevent chemical residue buildup.

4. Retest and Adjust: Allow water to circulate for 6–8 hours, then retest pH and alkalinity levels. Repeat the process in small increments if needed, avoiding over-dosing.

5. Safety Precautions:

   • Wear protective gloves and safety goggles during handling to avoid skin or eye contact.

   • Handle in a well-ventilated area to prevent inhalation of dust particles.

   • Do not mix with other chemicals, especially chlorine, oxidizers, or household cleaners, to avoid hazardous reactions.

   • Store in a cool, dry, well-ventilated area away from moisture, heat, and incompatible substances.
