Balanced Hardness for Clearer, More Stable Spa Water

SpaCare Calcium Hardness Enhancer is formulated to raise calcium hardness in spa and hot tub water, helping maintain balanced water and protect the spa environment as part of your regular care routine.

Calcium hardness plays an important role in overall water balance. When calcium levels are too low, spa water can become more aggressive toward surfaces and equipment, while balanced levels help maintain clearer, more stable water.

Made from quality calcium chloride, this clean-dissolving formula is ideal for use when testing shows calcium hardness is below the recommended range for your spa or hot tub surface type.

How It Works

Calcium hardness refers to the level of dissolved calcium in spa water. This forms an important part of overall water balance and should be maintained within the recommended range for your spa surface type.

SpaCare Calcium Hardness Enhancer adds calcium chloride to the water to raise calcium hardness when levels are too low. This helps maintain a more balanced spa environment, clearer water, and better ongoing protection for spa surfaces and equipment.

Balanced Calcium Hardness for Spa Water

How to Use

  • Test the spa water before treatment.
  • Determine the amount required based on your spa volume and current calcium hardness reading.
  • Dissolve the measured product in a bucket of water.
  • Pour slowly into the spa with the pump operating.
  • Allow the water to circulate fully after dosing.
  • Re-test the calcium hardness after treatment to confirm the level is within range.

Dosage & Coverage

  • Dosage: Add 10g per 1,000 litres of water to increase calcium hardness by 10ppm.

Important Usage & Compatibility Information

  • Always test the water before adding product and use a test kit to measure calcium hardness accurately.
  • Never add this product via the skimmer, as it releases heat while dissolving and may damage the skimmer basket or housing.
  • Do not overdose.

Maintain calcium hardness within the recommended range for your spa surface type: 200ppm–275ppm for concrete and tiled spas, and 175ppm–225ppm for other surfaces.

Frequently Asked Questions

Why is calcium hardness important in a spa or hot tub?
Calcium hardness is an important part of overall water balance. When it is within the recommended range, it helps maintain a more stable spa environment, clearer water, and better care for spa surfaces and equipment.
What can happen if calcium hardness is too low?
Water that is too low in calcium can become more aggressive over time. This may affect spa surfaces and equipment and can make water balance harder to maintain consistently.
Do all spas need the same calcium hardness level?
No. Recommended calcium hardness levels vary depending on the spa surface. Concrete and tiled spas and hot tubs need a higher range than spas with other surface types.
Why should I never add it through the skimmer?
Because it releases heat as it dissolves, this product can damage the skimmer basket or housing. Dissolve it in a bucket of water first, then pour it directly into the spa water.
