# Poolife Calcium Plus 93% Calcium Hardness Increaser 8 lb

Low calcium hardness can silently damage your pool by allowing water to become aggressive—etching plaster, corroding metal components, and shortening the life of heaters and equipment. **Poolife® Calcium Plus 93%** is a fast-dissolving, high-purity **calcium hardness increaser** designed to quickly restore proper calcium levels and protect your pool’s surfaces and systems.

This **8 lb bag** is ideal for routine maintenance, smaller pools, or targeted calcium adjustments, delivering professional-grade results in a convenient, easy-to-handle size.

### Raises Calcium Hardness to Prevent Corrosion & Etching

When calcium hardness is too low, pool water pulls minerals from plaster, grout, and metal components. This can lead to:

-   Surface etching and rough plaster
    
-   Heater and equipment corrosion
    
-   Staining and premature wear
    

Poolife Calcium Plus restores hardness levels efficiently, helping stabilize water chemistry and protect your investment.
