Using Calcium Chloride to Adjust Hardness

Calcium chloride is a quick and effective solution for increasing calcium hardness in your pool water. Proper calcium hardness is essential for protecting pool surfaces, equipment, and maintaining water clarity. If your pool water has low calcium levels, using calcium chloride can help you restore balance and prevent costly damage. With Aquazen7, managing calcium hardness is simple and hassle-free.

Why Adjust Calcium Hardness?

Maintaining the ideal calcium hardness range of 200-400 ppm is critical for:

1. Preventing Corrosion:

• Low calcium levels make water aggressive, leading to corrosion of metal components, pool liners, and grout.

1. Avoiding Surface Damage:

• Soft water leaches calcium from plaster and tile surfaces, causing etching and discoloration.

1. Ensuring Equipment Longevity:

• Proper calcium levels protect pumps, heaters, and filters from damage caused by soft water.

1. Improving Water Quality:

• Balanced calcium hardness ensures clear, sparkling water that’s inviting to swimmers.

Aquazen7 Tip: Regularly test calcium hardness levels to ensure they remain within the optimal range.

How to Use Calcium Chloride

1. Test Calcium Hardness:

• Use a reliable water testing kit to determine the current calcium hardness level.

1. Calculate the Amount of Calcium Chloride Needed:

• To raise calcium hardness by 10 ppm, add 1.25 pounds of calcium chloride per 10,000 gallons of water.
• Example: To raise calcium hardness from 150 ppm to 250 ppm in a 10,000-gallon pool, add 12.5 pounds of calcium chloride.

1. Dissolve the Calcium Chloride:

• Fill a bucket with warm water and slowly add the calcium chloride while stirring to dissolve it completely.

1. Add to the Pool:

• Pour the dissolved solution evenly around the pool while the pump is running to ensure even distribution.
• Avoid adding directly to skimmers or concentrated areas to prevent damage.

1. Retest the Water:

• Allow the pump to circulate water for 6-8 hours and retest calcium hardness levels.

Aquazen7 Tip: Gradually add calcium chloride to avoid overshooting the target range.

Best Practices for Using Calcium Chloride

• Always Pre-Dissolve:
• Adding undissolved calcium chloride directly to the pool can cause staining or cloudiness.
• Monitor pH and Alkalinity:
• Adding calcium chloride can slightly raise pH levels. Adjust pH if needed to maintain the ideal range of 7.2-7.6.
• Use in Small Increments:
• It’s better to add less and retest than to overcorrect and require dilution.

Aquazen7 Tip: Combine calcium adjustments with Aquazen7 One-Step Pool Solution for balanced water chemistry.

Common Issues and Solutions

1. Cloudy Water After Adding Calcium Chloride:

• This is usually temporary and clears with proper circulation.
• Ensure calcium chloride is fully dissolved before adding to the pool.

1. Overcorrecting Calcium Levels:

• High calcium hardness can cause scaling and cloudy water. If levels exceed 400 ppm, dilute the pool water by partially draining and refilling with fresh water.

Aquazen7 Tip: Test water frequently to avoid overcorrection and maintain balanced water chemistry.
