BioGuard Balance Pak 300 Calcium Hardness Increaser, 7 lb

Overview

BioGuard Balance Pak 300 is a calcium hardness increaser designed to help maintain a balanced pool environment. By raising calcium hardness, it can reduce the risk of corrosion to metal equipment, etching of plaster, and wrinkling of vinyl liners. The result is a steadier water balance that supports effective use of other pool chemicals and contributes to a more inviting swim space.

Fast, palletized formula for clearer water

This product features a unique palletized formulation that dissolves quickly, delivering calcium where it’s needed with minimal cloudiness. A faster dissolve and clearer water appearance can help you see results sooner, making routine maintenance more straightforward.

Key benefits

• Rises calcium hardness quickly and simply with a palletized formulation for faster dissolving and clearer water.
• Helps protect pool equipment from corrosion, contributing to longer equipment life and peace of mind.
• Supports the integrity of plaster and vinyl surfaces by helping to prevent etching and liner wrinkling.
• Assists with overall water balance, which can make the application of other pool chemicals more predictable.
• BioGuard is a trusted name in pool care, offering solutions designed for reliability and ease of use.

How Balance Pak 300 works

Balance Pak 300 is formulated to raise calcium hardness levels in circulating pool water. When added, its pellets dissolve and contribute to a more stable hardness range. A well-balanced level can support smoother plaster and a consistent surface feel, while helping to minimize common balance-related issues.

What to expect and usage tips

Results depend on your current water chemistry, pool type, and usage. Many pool owners notice steadier water balance and reduced risk of finish issues as hardness increases. To use effectively:

• Test water regularly and adjust toward the target calcium hardness range.
• Broadcast the pellets around the deep end with the circulation system running to promote even dissolution.
• Allow the formulation to dissolve completely, then re-test before adding additional chemicals.

Consider Balance Pak 300 as part of a balanced pool care routine to support long-term water clarity and surface protection without making promises—results may vary with conditions.
