Spa Fresh ULTRA Cal up 1kg

Product Description

Spa Fresh ULTRA Cal Up 1kg is a specialised water balancing treatment formulated to increase calcium hardness levels in spa, hot tub and swim spa water. Maintaining the correct calcium hardness helps protect spa surfaces, heaters and metallic components from corrosion, etching and premature wear caused by soft or aggressive water. 

Low calcium hardness can lead to water becoming corrosive, which may damage spa equipment and surfaces over time. Spa Fresh ULTRA Cal Up restores calcium hardness to recommended levels, helping to maintain balanced water chemistry, improve equipment longevity and provide a more stable spa environment. 

Regular testing and adjustment of calcium hardness is an important part of a complete spa water care program, especially when filling a spa with soft water or after water replacement.
