Pool Mate 40-Pounds Premium Alkalinity Increaser - Stabilizes pH

In this review the Pool Mate 40-Pounds Premium Alkalinity Increaser is evaluated for pool owners who need a straightforward way to raise and stabilize total alkalinity. The bottom line: this is a simple, economical sodium bicarbonate product that reliably increases alkalinity and helps prevent pH bounce, making it a good fit for routine maintenance. It is especially useful for pools where fluctuating pH causes cloudy water or extra chemical use, and the review highlights ease of use, clear dosing guidance, and measurable performance.

Key Features

• 100% Sodium Bicarbonate: A single-ingredient formula that raises total alkalinity without adding unexpected chemicals to pool water.
• Alkalinity Control: Designed to maintain total alkalinity in the recommended range to help keep pH stable and reduce pH bounce.
• Clear Dosing Guidance: The included table shows that 11 ounces raises alkalinity about 10 ppm per 5,000 gallons, making it easy to dose accurately.
• Fast Dissolving: The powder dissolves quickly when added with the pump running, so it mixes into the pool water without long waiting periods.
• Protects Pool Surfaces: Regular use helps prevent equipment corrosion, scale formation and etching of pool surfaces by keeping alkalinity within target ranges.

Who It's For

This product is best for homeowners with in-ground or above-ground pools who test their water regularly and want a cost-effective, no-frills way to raise total alkalinity. It suits people trying to reduce frequent pH adjustments or those who have experienced staining, corrosion or cloudy water due to low alkalinity.

It is not aimed at users who need multi-chemical formulations or those unfamiliar with basic pool testing; if you do not test total alkalinity or prefer pre-mixed algaecide/clarifier combos, you should look elsewhere. Pool technicians and DIY maintainers who measure water chemistry will get the most value from this product.

Pros & Cons

Pros

• Effective at raising total alkalinity to the recommended range when dosed per the instructions.
• Single-ingredient formula reduces risk of adding unwanted compounds to pool water.
• Customers report good value for money compared with household alternatives.
