Description
Crystal Water Calcium Hardener (750g) – Surface & Equipment Protector
Protect your investment with Crystal Water Calcium Hardener. If your spa water is too "soft" (low calcium hardness), it becomes aggressive, actively seeking minerals by leaching them from your spa’s surfaces, heater elements, and internal seals.
This high-purity formula increases the calcium levels in your water, creating a balanced environment that prevents costly etching, pitting, and corrosion.
Why Calcium Hardness Matters:
-
Prevents Equipment Corrosion: Stops soft water from "eating away" at metal heater elements and rubber seals, extending the life of your pump and heater.
-
Surface Protection: Prevents the etching and degradation of acrylic, fiberglass, and tiled surfaces that occurs when water is mineral-deficient.
-
Reduces Foaming: Properly balanced calcium levels help reduce the tendency of spa water to foam excessively when the jets are turned on.
-
Stable Water Chemistry: Helps maintain overall water balance, making it easier to keep your pH and Alkalinity in check.

Application Instructions
-
Test your water using a kit that measures Calcium Hardness. The ideal range for spas is 150 – 250 ppm.
-
If levels are below 150 ppm, calculate the required dose (refer to the bottle label for your specific spa volume).
-
Dissolve the granules in a bucket of water first, then pour the solution into the spa while the pumps are running.
-
Allow the water to circulate for at least 2 hours before re-testing.
