Pool Mate Alkalinity Increaser for Swimming Pools — 10 lb Sodium Bicarbonate, Fast-Dissolving pH Stabilizer

Pool Mate 10-Pounds Premium Alkalinity Increaser is a sodium bicarbonate formula designed to raise and stabilize total alkalinity in swimming pools quickly and safely.

Keeping total alkalinity in the correct range helps your sanitizer work efficiently and reduces pH swings that can damage finishes and equipment. Pool Mate’s alkalinity increaser dissolves easily and is simple to add while your pump runs. Use a reliable test kit to measure total alkalinity before adding product and follow the dosing table included with the package for accurate results.

How does Pool Mate raise and stabilize my pool’s water?

Pool Mate supplies sodium bicarbonate, which increases the water’s buffering capacity so pH changes occur more slowly. Raising total alkalinity reduces rapid pH “bounce,” making it easier to maintain the ideal pH range with routine adjustments.

• Sodium bicarbonate is the active ingredient for controlled alkalinity increases.
• Dissolves quickly when added with the pump running to distribute evenly.
• 11 ounces raises alkalinity by approximately 10 ppm per 5,000 gallons.

What alkalinity levels should I aim for with different pool surfaces?

Target alkalinity ranges vary by pool construction because some finishes are more sensitive to water chemistry. Check the type of your pool surface and adjust total alkalinity to the recommended range to protect finishes and maintain balanced water.

• Fiberglass pools: aim for 70–100 ppm to protect the gel coat.
• Marcite, painted, tile, exposed aggregate: aim for 80–120 ppm for stable water.
• Vinyl-lined pools: maintain 120–140 ppm to minimize shrinkage and stress on the liner.

How much should I add and how do I apply it safely?

Add Pool Mate directly to the pool while the circulation pump is running so the product disperses evenly. Always measure total alkalinity before adding, follow the included dosing table, and avoid adding other chemicals within a short time frame to prevent interactions.

• Test TA with a reliable kit and calculate dosage from the package table.
• Broadcast evenly around the deepest part of the pool while the pump runs.
• Allow several hours for circulation and retest before making additional adjustments.

Will this product help prevent equipment damage or surface etching?

Maintaining proper total alkalinity reduces aggressive water conditions that can lead to metal corrosion or plaster scaling. While alkalinity increaser helps stabilize water, regular testing and overall water balance management are needed to protect pool hardware and finishes.

• Stabilized alkalinity helps prevent rapid pH shifts that contribute to corrosion.
• Consistent TA supports plaster and tile longevity by reducing etching risk.
• Works with other balance practices—monitor calcium hardness and pH too.

Who is this for: Pool Mate 10-Pounds Premium Alkalinity Increaser is for pool owners and maintenance professionals who need a straightforward way to raise total alkalinity and reduce pH instability. It is suitable for fiberglass, plaster, tile, and vinyl pools when used according to the dosing guidance—ideal for seasonal balancing, routine maintenance, or after heavy rain or chemical shocks that lower alkalinity.
