Low calcium hardness can quietly damage your pool—etching plaster, corroding metal components, and shortening the life of heaters and equipment. Poolife® Calcium Plus (93%) is a professional-strength calcium hardness increaser designed to quickly and effectively raise calcium levels, protecting pool surfaces and maintaining proper water balance.

This high-purity, fast-dissolving formula is ideal for pools with soft water, frequent refills, or aggressive water conditions. With a large 25 lb pail, it’s well-suited for ongoing maintenance, startups, and service professionals who need reliable results.


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.


High-Purity 93% Formula for Fast Results

This product contains 93% calcium chloride, allowing it to dissolve rapidly and deliver predictable results. The high concentration means:

  • Faster correction of low hardness levels

  • Less product required compared to lower-grade formulas

  • Reliable dosing for consistent water balance

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


Ideal for New Pools, Refills & Soft Water Areas

Poolife Calcium Plus is commonly used:

  • During new pool startups

  • After partial or full water drains

  • In regions with naturally soft water

  • When calcium hardness tests below recommended range

Maintaining proper hardness helps prevent damage before it starts.


Compatible with All Pool Types

This calcium hardness increaser is safe for:

  • Chlorine pools

  • Saltwater pools

  • Plaster, pebble, vinyl, and fiberglass surfaces

When used according to label directions, it integrates smoothly into standard pool maintenance programs.
