How to Raise Alkalinity in a Pool Without Affecting PH?

Maintaining the perfect water balance in your swimming pool is essential for both swimmer comfort and the longevity of your pool equipment. One of the most crucial but often misunderstood aspects of pool chemistry is total alkalinity. Many pool owners struggle with how to raise alkalinity in the pool without affecting pH, as these two factors are closely linked.

At Anomaly Pool Services, we specialize in helping pool owners achieve optimal water chemistry with expert advice and professional maintenance. In this comprehensive guide, we’ll explain:

• The role of swimming pool alkalinity and its relationship with pH
• Step-by-step methods to raise alkalinity without disrupting pH
• The best alkalinity increaser for swimming pools
• Common mistakes to avoid
• Expert tips from Anomaly Pool Services

By the end of this article, you’ll have a clear understanding of how to maintain balanced pool water effortlessly.

Understanding Swimming Pool Alkalinity and pH

Before adjusting your pool’s chemistry, it’s crucial to understand what alkalinity is and why it matters.

What Is Total Alkalinity?

Total alkalinity (TA) measures the water’s ability to resist pH changes by neutralizing acids. It acts as a buffer, preventing sudden spikes or drops in pH.

• Ideal range: 80–120 ppm (parts per million)
• Low alkalinity (below 80 ppm): Causes pH fluctuations, corrosion, and skin irritation.
• High alkalinity (above 120 ppm): Leads to cloudy water, scaling, and reduced chlorine efficiency.

The Relationship Between Alkalinity and pH

Since alkalinity stabilizes pH, increasing it often raises pH as well. However, certain methods allow you to raise alkalinity without significantly affecting pH, which is crucial for maintaining balanced water.

How to Raise Alkalinity in a Swimming Pool Without Affecting pH

If your pool’s alkalinity is too low, follow these proven methods to increase it while keeping pH stable.

Use Sodium Bicarbonate (Baking Soda)

The safest and most effective alkalinity Increaser for swimming pools is sodium bicarbonate (baking soda). Unlike soda ash (which raises pH significantly), baking soda primarily increases alkalinity with minimal pH impact.

Step-by-Step Guide to Adding Baking Soda

• Test Your Water: Use a reliable test kit to check current alkalinity and pH levels.
• Calculate the Required Dosage: 1.5 lbs of baking soda per 10,000 gallons raises alkalinity by 10 ppm. Adjust the amount based on your pool size and current TA levels.
• Pre-Dissolve the Baking Soda: Mix it in a bucket of water to prevent cloudiness.
• Add Slowly Around the Pool: Distribute evenly near the return jets for better circulation.
• Wait 4–6 Hours & Retest: Allow the water to circulate before testing again.

Air out the Water to Balance pH

If your pH rises slightly after adding baking soda, aeration can help lower it naturally without affecting alkalinity.

Effective Aeration Methods

• Run water features (fountains, waterfalls, deck jets).
• Point return jets upward to create surface agitation.
• Use a pool aerator or air compressor.

Avoid Soda Ash (pH Increaser)

While soda ash (sodium carbonate) raises both pH and alkalinity, it’s not ideal if you only want to increase alkalinity. Stick to baking soda for better control.

Use a Commercial Alkalinity Increaser

If you prefer a pre-measured solution, commercial alkalinity Increasers (like Arm & Hammer Pool Care Alkalinity Up or Clorox Pool&Spa Alkalinity Booster) are convenient alternatives.

Best Alkalinity Increaser for Swimming Pools

Choosing the right product is crucial for maintaining balance. Here are the top options recommended by Anomaly Pool Services:

Pure Baking Soda (Sodium Bicarbonate)

Pros

• Affordable and easily available.
• Minimal impact on pH.
• Safe for all pool types.

Cons

Requires precise measurement.

Commercial Alkalinity Boosters

Pros

• Pre-measured for convenience.
• Fast-dissolving formulas.

Cons

Slightly more expensive than baking soda.

Natural Alternatives (Limited Use)

• Borax: Raises pH more than alkalinity.
• Aeration + Baking Soda: Best for controlled adjustments.

Common Mistakes When Adjusting Alkalinity

Many pool owners make these errors when trying to balance their water:

Using pH Increaser (Soda Ash) Instead of Baking Soda

Soda ash raises pH too quickly, making it harder to stabilize.

Adding Chemicals Too Quickly

Always add alkalinity Increaser gradually and retest before adding more.

Ignoring Aeration After Adjustments

Aeration helps stabilize pH if it rises slightly after adding an alkalinity Increaser.

FAQs: Raising Pool Alkalinity Without Affecting pH

Can I use baking soda to raise alkalinity without changing pH?

Yes! Baking soda is the best option because it has a minimal effect on pH compared to soda ash.

How long does it take to raise alkalinity in a pool?

After adding baking soda, wait 4–6 hours before retesting. Full circulation may take up to 24 hours.

What if my pH rises too much after adding an alkalinity Increaser?

Use aeration or a pH reducer (muriatic acid) in small doses to bring pH back down.

How often should I check my pool’s alkalinity?

Test alkalinity at least once a week, especially after heavy rain or chemical adjustments.

Can low alkalinity damage my pool?

Yes! Low alkalinity leads to:

• Corroded equipment
• Stained surfaces
• Unstable pH levels
