SpaCare Calcium Up is used to raise the calcium hardness of the water to avoid corrosion in your spa.

By using this product, you prevent damage to the tub in areas with soft water. (For water treatment where a softening plant is used)

Use a hardness tester or test strips to be sure you measure the water hardness correctly – a calcium hardness of 200-300 mg/l CaCO₃ is recommended.
