### Raises Calcium Hardness to Protect Pool Surfaces

Proper calcium hardness helps prevent water from becoming corrosive. When levels are too low, water pulls calcium from plaster, grout, and metal surfaces—leading to:

-   Surface etching and roughness
    
-   Staining and discoloration
    
-   Heater and equipment corrosion
    

Poolife Calcium Plus raises hardness levels quickly, helping stabilize water and protect long-term investments.
