Calcium 150 increases the calcium hardness level in your spa water to help prevent corrosion and equipment damage such as heater or pump deterioration. Low calcium levels (soft water) can cause surface etching and imbalance in your water chemistry. This product helps maintain optimal hardness levels for balanced, healthy, and long-lasting spa water.

FAQ


Adjusting calcium hardness is essential for protecting your spa and keeping the water stable. Low calcium hardness makes the water corrosive, which can damage surfaces, heaters, jets, and other components over time. High calcium hardness, on the other hand, leads to cloudy water, scale buildup, and calcium deposits inside the spa and plumbing. Keeping calcium hardness in the ideal range of 100–200 ppm helps prevent corrosion, reduces scale formation, and keeps the water clearer, more stable, and more comfortable for bathers.

This is the amount of dissolved calcium in the water. Proper hardness protects the acrylic, heat exchanger, and metal parts. Indicative targets: 100–200 ppm for spas. Too low → “aggressive” water, risk of corrosion and foaming; too high → limescale deposits (white marks), cloudy water, and clogged filters.


To increase the water hardness in a spa, you need to use a "calcium hardness enhancer" (also called "Calcium Plus"). The ideal hardness for a spa is generally between 100 and 200 ppm. Water that is too hard makes it corrosive, which can damage the equipment, the heater, and even the spa's liner. To correct the hardness, add the recommended amount of product based on the spa's volume, let the water circulate for 20 to 30 minutes, and then test again. Always increase the hardness gradually to avoid exceeding the optimal level.

There is no direct chemical product to lower the water hardness of a spa. To reduce excessive hardness, the most effective solution is to partially or completely drain the spa and refill it with softer water (filtered, softened, or tap water with a lower mineral content). Water that is too hard can cause limescale buildup, cloudiness, and reduced heater performance. After refilling, the pH and alkalinity should be adjusted to stabilize the water.
