Spa Fresh ULTRA Cal up 500gm

Product Description 

Spa Fresh ULTRA Cal Up 500g is a water balancing treatment specifically formulated to increase calcium hardness levels in spa, hot tub and swim spa water. Maintaining proper calcium hardness is essential for protecting spa equipment, heaters, acrylic surfaces and plumbing components from the damaging effects of soft or aggressive water. 

Water that is low in calcium hardness can become corrosive, leading to etching of surfaces, deterioration of metallic components and reduced equipment lifespan. Spa Fresh ULTRA Cal Up restores calcium hardness to recommended levels, helping create balanced water conditions while protecting your investment. 

As part of a complete spa water care program, regular calcium hardness testing and adjustment help improve water stability, reduce corrosion risks and support effective water balance.
