BioGuard Balance Pak 300 - 12 lb

Calcium Hardness Increaser for Stronger Pool Water Balance

BioGuard Balance Pak 300 is a calcium hardness increaser designed to raise low calcium hardness levels in swimming pool water. This 12 lb size is a strong choice for pool owners who need a larger supply for seasonal balancing, fresh-fill adjustments, or ongoing correction of soft pool water.

Low calcium hardness can make pool water aggressive, which may contribute to equipment corrosion, plaster etching, liner wrinkling, staining, and surface deterioration. BioGuard Balance Pak 300 helps restore calcium hardness to a healthier range so pool water is better balanced and less likely to damage pool surfaces and equipment.

Its quick-dissolving formula is made for direct pool application and helps reduce cloudiness compared with similar calcium hardness products.

Key Benefits

• Raises calcium hardness: Helps correct low calcium hardness in swimming pool water.

• Quick-dissolving formula: Designed for faster dissolving and less cloudy application.

• Helps prevent corrosion: Supports protection of pool equipment and metal components.

• Protects pool surfaces: Helps prevent plaster etching, surface staining, and finish deterioration caused by low calcium hardness.

• Helps prevent liner wrinkling: Supports better water balance for vinyl liner protection.

• Larger 12 lb size: Useful for bigger pools, fresh-fill adjustments, and seasonal water balancing.

• Direct pool application: Scatter over the pool water surface as directed, with no pre-dissolving required.

Product Details

Compatibility and Requirements

BioGuard Balance Pak 300 is designed for swimming pool water balancing when calcium hardness is below the recommended range. It is useful for pool owners who need to protect plaster, liners, equipment, and other pool surfaces from the effects of overly soft water.

Before applying, test calcium hardness with a reliable test kit or professional water analysis. Add only the amount needed based on current hardness level, pool volume, and label directions. Do not pre-dissolve this product because heat can be generated when it contacts water.

How to Use

Test Calcium Hardness

Test pool water before adding BioGuard Balance Pak 300. Calcium hardness should generally be maintained in the recommended range, and product should only be added when testing shows that hardness is too low.

Apply Directly to Pool Water

Scatter the required dose directly over the pool water surface. Do not pre-dissolve. Use a surface-compatible pool brush to move any undissolved granules away from pool surfaces.

Standard Dose

Use 1 lb per 10,000 gallons to raise calcium hardness by approximately 10 ppm. For a 40 ppm increase, use 4 lb per 10,000 gallons.

Retest Before Additional Treatment

Allow the water to circulate thoroughly, then retest calcium hardness before adding more product. Avoid overcorrection, since excessive calcium hardness may contribute to scale.

Frequently Asked Questions

What does BioGuard Balance Pak 300 do?

BioGuard Balance Pak 300 raises calcium hardness in swimming pool water. Proper calcium hardness helps protect pool equipment, plaster, liners, and surfaces.

Why is calcium hardness important?

When calcium hardness is too low, pool water may become aggressive and contribute to corrosion, plaster etching, staining, liner wrinkling, and surface damage.

How much does the 12 lb size treat?

At the standard reference rate of 1 lb per 10,000 gallons to raise calcium hardness by about 10 ppm, a 12 lb container provides up to twelve 10 ppm treatments for a 10,000 gallon pool.

Should I pre-dissolve Balance Pak 300?

No. Do not pre-dissolve BioGuard Balance Pak 300. Add it directly to the pool water as directed.

Is this product quick-dissolving?

Yes. BioGuard Balance Pak 300 is described as a quick-dissolving calcium hardness increaser with less cloudy application than similar products.
