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.

High-Purity 93% Calcium Chloride for Fast Results

Formulated with 93% calcium chloride, this product dissolves quickly and delivers predictable hardness increases. The high concentration means:

• Faster correction of low calcium levels

• Less product required than lower-grade formulas

• Consistent, reliable dosing

It’s especially effective after water replacement or during pool startup.

Ideal for Soft Water Areas & Routine Adjustments
