Keep your hot tub water better balanced with Mineraluxe Calcium Plus 550 g.
 

 
When calcium hardness is too low, hot tub water can become aggressive and may try to pull minerals from other surfaces. This can contribute to corrosion of metal components, the heater and other equipment. Low calcium hardness can also affect overall water balance and make hot tub care harder to manage.
 

 
Mineraluxe Calcium Plus is a calcium hardness increaser designed to raise calcium levels when they are too low. It helps protect hot tub surfaces, metal components and equipment while supporting better overall water balance.
 

 
Proper calcium hardness also helps improve bather comfort, chemical efficiency and water stability. It is an essential product to keep on hand, especially after a fresh fill, after a water test, or when source water is naturally soft.
