SpaGuard® Calcium Hardness Increaser is designed to raise calcium hardness levels in spa water when they fall too low, helping prevent corrosion of equipment and surface etching.
The granular or liquid formula dissolves quickly in circulating spa water and delivers measurable increases: for example, “1 tablespoon per 100 gallons increases calcium hardness by ~25 ppm.”
Maintaining proper calcium hardness (typically ~100-200 ppm for spas) helps protect plumbing, jets, surfaces and prevents foaming or water that feels “soft.”
Compatible with all spa sanitizing systems and easy to use—just test water first, then broadcast the product while the circulation is running.
Ideal for spas located in soft-water areas or where water replacement or fill has resulted in low calcium levels.

Directions

Use an accurate test kit to measure current calcium hardness level in your spa.

With the circulation system running, broadcast the required amount of product across the water surface (for example: 1 tablespoon per 100 gallons raises hardness ~25 ppm).

Continue circulation for at least 30 minutes to ensure full dispersion.

Retest calcium hardness after treatment. Adjust as needed.

Store the bottle tightly sealed in a cool, dry place; keep out of reach of children.

FAQ

Q: Why is calcium hardness important in a spa?

A: Low calcium hardness can lead the water to become corrosive, damaging jets, plumbing and surfaces. SpaGuard recommends maintaining levels in a proper range to prevent such damage.

Q: How quickly will this product work?

A: The formula is designed to dissolve quickly in circulating spa water; you should see results within the recommended circulation time.

Q: Can this product be used with any sanitizer system?

A: Yes — it is compatible with sanitizer systems such as chlorine, bromine, salt, ozone, etc. Provided water chemistry is balanced.

Q: What is the target range for calcium hardness?

A: For spas, many manufacturers suggest around 100-200 ppm; always refer to your spa manufacturer’s spec.

Q: What happens if calcium hardness is too high?

A: Excessive calcium hardness can lead to scale formation, cloudy water and increased cleaning; this product is for raising low levels only.
