How to Raise pH in Your Pool

The simplest way to raise the pool’s pH is by adding baking soda in the pool or soda ash.

Both are common pool chemicals that adjust the acidity and help stabilize water.

The ideal pH level is between 7.4 and 7.6, with an acceptable range of 7.2 to 7.8.

Staying within this range keeps the pool safe, comfortable, and balanced for swimmers.

Chemicals to Use

• Soda ash (sodium carbonate): Raises the pool’s pH quickly without affecting alkalinity much.
• Baking soda (sodium bicarbonate): Raises alkalinity first, with a slight boost to pH.
• Pool pH increaser products: Branded chemicals that are usually just soda ash.

Steps to Raise the pH

1. Test your pool water with test strips, a test kit, or a digital meter.
2. Turn on your pump and filter so the chemicals circulate.
3. Broadcast soda ash or baking soda evenly across the pool surface.
4. Wait 20 minutes to 24 hours depending on what chemical you used.
5. Retest the water and repeat if the pool’s ph level is still low.

Why pH Balance Matters in Pools

Maintaining the right ph level is not just about clear water, it protects your pool and everyone who uses it.

• Keeps chlorine effective: At low ph, chlorine burns off quickly and loses strength.
• Prevents algae and cloudy water: Balanced chemistry makes it harder for algae to grow.
• Protects pool equipment and pool surfaces: Too much acidity causes corrosion, while higher ph levels can lead to scale buildup.
• Ensures swimmer comfort: Water that is too acidic can irritate skin and eyes.

Step-by-Step Guide to Raising pH

Test and Measure First

• Use a test kit, test strips, or a digital tester.
• Take samples from the middle of the pool, away from jets or the skimmer.
• Record ph level and total alkalinity to get accurate dosing.

Choose the Right Chemical

• Soda ash: Best if you need to raise the ph quickly.
• Baking soda: Better if alkalinity is also low, since it raises alkalinity while boosting ph slightly.
• Combination: Sometimes both are needed if you have a low ph level and low alkalinity.

Apply Chemicals Correctly

• Run the pump and filter before adding anything.
• Broadcast evenly across the pool surface to avoid clumps.
• Wait about 20 minutes after soda ash or 6–24 hours after adding baking soda before retesting.

Dosage Guidelines for Raising pH

The amount of chemicals depends on pool size and how low the pH level is.

Always add in smaller amounts, then retest and adjust.

• Baking soda: 1.5 lbs per 10,000 gallons of water raises alkalinity by about 10 ppm. Use 3–4 lbs if pH is under 7.2.
• Soda ash: Around 12 oz per 10,000 gallons raises the pH by about 0.5.

Rule of thumb: Start with half the dose, verify the results, then add more if needed.

Common Pool Problems Fixed by Raising pH

Algae

• Green water often follows a low pH level because chlorine loses effectiveness.
• Treat with chlorine shock and algaecide, then adjust pH and alkalinity afterward.

Corrosion

• Acidic pool water damages ladders, liners, pipes, and tiles.
• Adding baking soda or soda ash helps protect your pool surfaces and equipment.

Cloudy Water and Scaling

• If ph is too low, cloudy pool water can develop quickly.
• If too high, minerals form scale. Learning how to lower pH in pool when needed helps keep the pool’s ph level balanced.

Tips for Accurate Pool Maintenance

• Always measure water depth, not pool wall height.
• Convert inches to feet: multiply by 0.0833.
• Use a pool volume calculator to determine gallons of water before adding pool chemicals.
• Keep alkalinity levels between 80–150 ppm to stabilize pH.
• Retest at least once a week, and more often in summer.

When to Call a Professional

Some situations call for expert help:

• If you have an irregularly shaped pool that makes dosing tricky.
• When the pool’s pH level keeps dropping even after adding chemicals.
• If you are sizing or installing new pool equipment like pumps, filters, or heaters that rely on a balanced system.
