Useful Information

Calcium Chloride is essential for adjusting the calcium hardness in your pool. Proper calcium levels are crucial for preventing both surface damage and scaling issues.

Why Calcium Hardness Matters:

Too Little Calcium: Can lead to the dissolution of pool surfaces like tiles and cement, causing potential damage.

Too Much Calcium: Can cause scaling on pipes, valves, pumps, and particularly on heat exchange equipment.

Recommended Calcium Levels:

Ideal calcium levels typically range between 100 and 500 parts per million (ppm), varying based on your pool type:

Adjusting Calcium Levels:

To Increase Calcium Hardness: Adding 1 kilogram of Calcium Chloride will raise the calcium level by 90 ppm in 20,000 liters of water.

To Decrease Calcium Hardness: Add fresh water with low calcium content. For existing high calcium levels, use a scale control product to manage excess calcium.

Additional Tips:

Calcium Hypochlorite Users: Be aware that this sanitiser adds calcium to your pool. Check your water supply’s hardness with your local water provider. If you notice scale build-up in your kettle, your water supply likely has high calcium levels.
