Poolife Alkalinity Plus 25 lb Pail

Unstable pH, constant chemical adjustments, and corrosive water conditions are often signs of low total alkalinity. Poolife® Alkalinity Plus is a professional-grade total alkalinity increaser and pH buffer designed to stabilize pool water chemistry and prevent damaging pH swings.

By raising total alkalinity into the proper range, this product helps lock pH in place, making your pool easier to manage while protecting surfaces, equipment, and swimmer comfort.

Raises Total Alkalinity to Stabilize Water Chemistry

Total alkalinity acts as a buffer for pH. When alkalinity is too low, pH becomes unstable and difficult to control. Poolife Alkalinity Plus:

• Raises total alkalinity to recommended levels

• Prevents rapid pH fluctuation (“pH bounce”)

• Creates a stable foundation for balanced water

Proper alkalinity is essential before adjusting pH or sanitizer levels.

Prevents Corrosion, Etching & Equipment Damage

Low alkalinity can lead to aggressive, corrosive water that damages:

• Heaters and heat exchangers

• Metal fittings and components

• Plaster and cement-based finishes

• Pool plumbing and circulation systems

By buffering pH and stabilizing water balance, Poolife Alkalinity Plus helps protect your pool’s most expensive components.

Improves pH Control & Reduces Chemical Use

When alkalinity is balanced:

• pH stays in range longer

• Fewer pH adjustments are needed

• Chlorine works more efficiently

• Overall chemical demand is reduced

This makes Poolife Alkalinity Plus an essential product for long-term pool care and cost control.

Ideal for Startups, Refills & Routine Maintenance

Poolife Alkalinity Plus is commonly used:

• During pool startup or seasonal opening

• After heavy rain or large water replacement

• When pH won’t hold steady

• As part of regular water balance maintenance

Correcting alkalinity first makes all other chemical adjustments more effective.

Compatible with All Pool Types

This alkalinity increaser is safe for:

• Chlorine pools

• Saltwater pools

• Plaster, pebble, vinyl, and fiberglass surfaces

It integrates smoothly with Poolife chemical systems and standard pool maintenance routines when used as directed.
