Pool Mate pH Up for Swimming Pools — 10 lb Sodium Carbonate pH Raiser, Fast-Acting Alkalinity Boost

Pool Mate 10-Pounds Premium pH Up is a sodium carbonate formula designed to raise and stabilize swimming pool pH quickly and safely when levels read low.

Keeping your pool pH in the optimal range prevents equipment damage, improves sanitizer performance, and makes water more comfortable for swimmers. This 10-pound container of Pool Mate pH Up provides a concentrated, easy-to-use source of alkalinity boost. Follow pool test results and the included dosing chart for stepwise adjustments; the product dissolves in a plastic pail and is introduced around the pool perimeter while the circulation system runs.

How do I use Pool Mate pH Up correctly?

Test your pool water first and only add pH Up when levels are at or below 7.2. Pre-dissolve the required amount in a plastic bucket, then slowly pour the solution along the pool perimeter with the pump running to promote even distribution. Wait at least one hour after application, then retest and repeat dosing if necessary until pH reaches 7.4–7.6.

• Always test pH and total alkalinity before adding product.
• Pre-dissolve in plastic—never add dry granules directly to the pool.
• Pour slowly around the pool while the circulation system is operating.
• Retest after one hour; reapply in small increments if needed.

What results can I expect and how quickly will pH change?

Pool Mate pH Up is formulated to raise pH rapidly because it contains sodium carbonate. The exact rise depends on pool volume, current pH, and alkalinity; most pools show measurable change after one hour of circulation. If the first dose doesn’t reach target pH, additional small doses allow controlled, gradual adjustment without overshooting.

• Noticeable pH increase within one circulation cycle (about 1 hour).
• Controlled dosing reduces risk of overshooting target pH.
• Follow the included dosing chart for pool-size guidance.
• Best results when total alkalinity is within the recommended range.

Is Pool Mate pH Up safe for pool surfaces and equipment?

When used as directed, sodium carbonate raises pH without causing surface etching that can occur with uncontrolled acidity. Proper application helps protect plaster, tile grout, metal fittings, and heater elements from corrosion associated with low pH. Always pre-dissolve granules and avoid adding concentrated dry product directly to the pool to prevent local high-concentration contact with surfaces.

• Helps prevent erosion and etching by correcting low pH.
• Use pre-dissolved solution to avoid concentrated contact points.
• Compatible with common pool materials when used per instructions.
• Maintaining pH 7.4–7.6 supports sanitizer effectiveness and comfort.

How should I store and handle this product safely?

Keep the container tightly closed in a cool, dry area away from children, pets, and acids. Use protective gloves and eye protection when mixing or handling to avoid irritation from dust or concentrated solution. Dispose of any unused dissolved solution according to local regulations; never mix with other chemicals except as instructed.

• Store in original container, sealed, away from moisture and acids.
• Wear gloves and eye protection while handling or mixing.
• Use only plastic buckets for pre-dissolving.
• Keep out of reach of children and pets.
