🧪 Calcium Chloride Flakes (77% CaCl₂)

Calcium Chloride Flakes (77%) are a high-purity, fast-dissolving calcium salt used for pool water balance, hardness correction, and general water treatment.
These flakes dissolve quickly without residue, making them ideal for raising calcium hardness in pool systems to prevent corrosion, etching, and equipment deterioration.

Suitable for commercial pools, hotels, leisure centres, and private pools, this product ensures stable water chemistry and helps maintain proper Langelier Saturation Index (LSI) levels.

✅ Key Features

• 77% CaCl₂ concentration – highly effective and fast dissolving

• Prevents corrosion of pool surfaces, heat exchangers, and metal fittings

• Helps maintain correct calcium hardness levels

• Low dust, clean-handling flakes

• Compatible with all types of pool systems, including saltwater pools

• Suitable for commercial dosing and manual application

⚙️ Technical Specifications

• Chemical formula: CaCl₂

• Purity: 77% calcium chloride

• Form: White flakes

• Solubility: Fully soluble in water, rapid dissolution

• Typical hardness increase:

  • 100 g per 10,000 L increases calcium hardness by approx. 7–10 ppm

• Packaging: Bags or tubs depending on supply

📍 Applications

• Swimming pools (public, commercial, private)

• Spa and wellness facilities

• Water treatment plants

• Industrial hardness control

⚠️ Safety Notes

• Add product directly to water, never water to product

• Use protective gloves and goggles

• Avoid contact with moisture before use (hygroscopic)

• Not to be mixed directly with sodium carbonate (risk of precipitation)

⭐ PRACTICAL DOSING AMOUNT

To raise CH by 50 mg/L in 10 m³, add:

~1 kg of Calcium Chloride flakes (77% CaCl₂)

Dosing Instructions

1. Measure approximately 1 kg of Calcium Chloride flakes.

2. Fill a clean bucket halfway with warm water.

3. Slowly add the flakes into the water (never water into flakes).

4. Stir until fully dissolved.

5. Pour the solution directly into the pool with circulation running.

6. Allow 1–2 hours for thorough mixing.

7. Test calcium hardness again.
