MAV AquaDoc Pool Alkalinity Increaser Sodium Bicarbonate 5 lb — Raises & Stabilizes Total Alkalinity

MAV AquaDoc Pool Alkalinity Increaser is a 5 lb sodium bicarbonate formula designed to raise and stabilize your pool’s total alkalinity for clearer, more balanced water.

Keeping total alkalinity within the right range helps prevent wild swings in pH and supports comfortable, equipment-friendly pool water. AquaDoc’s Alkalinity Up uses high-quality sodium bicarbonate to quickly increase alkalinity without complicated mixing, making routine pool maintenance faster and more predictable.

How quickly will this sodium bicarbonate raise my pool’s alkalinity?

A single application of this product works rapidly once dissolved in pool water, with results measurable within hours depending on circulation. For best results, add while the pump is running and retest alkalinity after a few hours.

• Add directly to water—no pre-mixing required.
• Works faster with good pump circulation and return jets on.
• Retest after 4–8 hours and adjust dose if needed.
• Typical treatment quantities vary by pool volume and starting alkalinity.

What is the correct way to add AquaDoc Alkalinity Up to my pool?

Pour measured amounts around the deep end or in front of return jets while the pump runs to distribute the product evenly. Avoid adding all powder to one spot and always follow package dosing guidelines and safety directions.

• Wear gloves and keep dry scoop; avoid inhalation of dust.
• Broadcast slowly around the pool perimeter with pump on.
• Allow circulation for several hours before retesting alkalinity and pH.
• Store sealed in a cool, dry place to preserve effectiveness.

Will raising alkalinity affect my pool’s pH or equipment?

Increasing total alkalinity helps buffer the water and reduce pH swings, which can protect liners, heaters, and metal components. Proper alkalinity contributes to more stable pH, potentially reducing the need for frequent pH adjustments.

• Buffers against rapid pH changes for steadier water chemistry.
• Can help lower corrosive conditions and limit scale formation when balanced properly.
• Regular monitoring keeps alkalinity within the target range for equipment protection.
• Use alongside routine sanitizer and calcium hardness checks for best results.

How much product do I need for a typical backyard pool?

Dosing depends on pool volume and current alkalinity levels. Consult the product label for precise measurements, then retest and repeat small additions until you reach the desired total alkalinity range.

• 5 lb bag treats different volumes depending on how many ppm you need to raise.
• Smaller incremental additions are safer than large single doses.
• Keep a log of treatments to simplify future balancing.
• Combine with professional water test results for accurate dosing.
