Alkalinity Increaser 25 lb - Raises Alkalinity and Balances pH

Our review of this 25 lb alkalinity increaser finds it best for pool owners who need a straightforward way to stabilize water chemistry. The biggest reason to buy is its simple, single-ingredient formula of 100% sodium bicarbonate that reliably raises total alkalinity and helps maintain pH and chlorine effectiveness. For those who prefer a no-frills approach to pool balancing, this product delivers predictable results using the clear dosing guidance provided by the manufacturer.

Key Features

• 100% Sodium Bicarbonate: A pure active ingredient that increases alkalinity without adding other compounds that could cloud water.
• Maintains pH and Chlorine: By stabilizing alkalinity, it helps prevent pH swings that can reduce chlorine effectiveness.
• Precise Dosing Guidance: Adding 1.5 lbs per 10,000 gallons raises alkalinity by about 10 ppm, making adjustments predictable.
• Prevents Irritation: Proper alkalinity helps avoid high-pH skin rashes and low-pH eye stinging for swimmers.
• Summer Performance: Keeps water refreshing and stable even in hot weather when chemistry tends to drift.

Who It's For

This product suits residential pool owners who want an affordable, easy-to-use balancer to keep their pool's total alkalinity in the recommended 90-120 ppm range. It is particularly useful for those who test regularly and prefer to make incremental adjustments with a predictable, single-ingredient powder.

It is not targeted at people who need a multi-purpose chemical or complex shock treatment in one product; if you require combined chlorine management or stain control, look for specialized formulations designed for those tasks.
