Full Product Description +

Stable water chemistry starts with proper total alkalinity. When alkalinity levels fall too low, pool water becomes difficult to balance, pH fluctuates rapidly, and surfaces and equipment are placed under unnecessary stress. Poolife Alkalinity Plus is a high-purity sodium bicarbonate formula designed to safely and effectively raise total alkalinity in swimming pool water, creating a more stable foundation for overall water balance.

This 10 lb bag is ideal for routine water maintenance, seasonal startups, or corrective treatments when alkalinity readings fall below recommended ranges. By increasing total alkalinity, Poolife Alkalinity Plus helps buffer pH changes, making it easier to maintain consistent, comfortable water conditions.

Trusted by pool professionals and homeowners alike, this product delivers predictable results without introducing unwanted additives or byproducts.


Helps Stabilize Pool Water Chemistry

Total alkalinity acts as a buffer that protects pH from rapid swings. When alkalinity is too low, even small chemical additions or environmental factors can cause pH levels to shift dramatically.

Poolife Alkalinity Plus raises alkalinity efficiently, helping pH remain more stable over time. This reduces the need for constant chemical adjustments and supports a more balanced, manageable pool environment.


High-Purity Sodium Bicarbonate Formula

This product uses high-quality sodium bicarbonate, the industry-standard chemical for increasing total alkalinity. The granular formula dissolves easily and disperses evenly throughout the pool, allowing for controlled and accurate dosing.

Because it contains no unnecessary fillers, Poolife Alkalinity Plus delivers consistent performance and reliable results when used according to label instructions.


Suitable for Residential and Service Use

The 10 lb bag size makes this product convenient for homeowners while still being practical for service technicians performing regular water balance adjustments. It’s commonly used during pool openings, after heavy water replacement, or when correcting chronic alkalinity issues.

Maintaining proper alkalinity helps protect pool surfaces, heaters, and circulation equipment from damage caused by aggressive or unstable water.


Why Maintaining Proper Alkalinity Matters

Low total alkalinity can lead to ongoing water balance problems.

Raising alkalinity helps:

  • Stabilize pH levels

  • Reduce rapid chemical fluctuations

  • Protect pool surfaces and equipment

  • Improve overall water balance consistency

Keeping alkalinity within the recommended range simplifies pool care and improves long-term system performance.
