High-Performance Calcium Hardness Increaser for Pool Maintenance

  • Elevates Calcium Levels Safely and Efficiently: Our calcium hardness increaser rapidly increases pool calcium levels, preventing erosion, pitting, and etching of pool surfaces.

  • Prevents Scaling and Blockage: Excessive use of this product does not lead to scaling or blockage, ensuring that your pool equipment remains in optimal condition.

  • Improves Water Quality: Maintain the ideal calcium hardness range for enhanced water clarity and pH balance.

  • Optimal Usage: The recommended range for calcium hardness is 180-220 ppm, with a maximum of 400 ppm. Add approximately 6 pounds for every 10,000 gallons of water to increase hardness by 50 ppm.

  • Apply When Necessary: Apply this product if your calcium hardness drops below 150 ppm, ensuring your pool remains in top condition.
