Leslie's Soda Ash is the number one choice when it comes to raising your pool's pH levels. Made of 100% sodium carbonate, Soda Ash pH Up increases the pH and Total Alkalinity in the water to make it less acidic. This powerful formula is the most concentrated pH and Total Alkalinity increaser you can find. It dissolves quickly in its granular form and goes to work immediately to increase your pool's pH and alkalinity. Lower pH levels can cause corrosion, stains, and irritation to swimmers, so we recommend Leslie's Soda Ash pH Up to keep your pool water balanced and safe. One pound of Soda Ash per every 10,000 gallons is all you will need to turn your pH levels around.

Importance of pH

When your pool's water is lacking the proper amount of pH, the available chlorine in your water starts to dissipate causing you to spend more out of pocket to replenish. Corrosion and oxidation of metals, etching and erosion of plaster and grout surfaces, and plastic and vinyl becoming brittle are all effects of low pH levels. Leslie's Soda Ash pH Up will help increase your pH quickly and easily.

Raising Total Alkalinity and pH

The ideal pH ranges for most swimming pools should be between 7.4 and 7.6 for pH, and between 80 and 140 ppm for Total Alkalinity. When pH levels are too low, this means the water has become overly acidic. Too much acid can cause things like corrosion of pipes and pool fixtures, plaster stains or etching, and eye, nose, and skin irritation for swimmers. Balanced Total Alkalinity is necessary to keep your pH levels balanced as well, and low Total Alkalinity can also cause damage to pools and irritation for swimmers. Leslie's Soda Ash quickly raises both pH and Total Alkalinity levels to more acceptable ranges with ease. Just add 1lb of Soda Ash for every 10,000 gallons in your swimming pool.

Keep your pool pH and Total Alkalinity balanced with ease when you use Leslie's Soda Ash.

Common Questions:

What is Leslie's Soda Ash made of?
  • Leslie's Soda Ash is made of 100% sodium carbonate, a fast-dissolving granular compound that raises both pH and Total Alkalinity in pool water.
How much Soda Ash should I use to raise pH?
  • If your pool’s pH is below 7.2, add 1 lb per 10,000 gallons of water. Do not exceed 4 lbs per 10,000 gallons in a single treatment to avoid overcorrection.
Is Soda Ash safe for all pool surfaces and swimmers?
  • Yes! It’s safe for fiberglass, vinyl, plaster, and tile pools, and helps prevent corrosion and irritation. You can swim after 4 hours of circulation once the product is fully dissolved.
Should I retest my water after using Soda Ash?

Definitely. Always retest pH and Total Alkalinity after each dosage to ensure levels are within the ideal ranges:

  • pH: 7.4–7.6
  • Total Alkalinity: 80–140 ppm
Why is it important to maintain proper pH and Total Alkalinity?
  • Low pH and alkalinity can lead to corrosion of pool equipment, etching of surfaces, and irritation for swimmers. Balanced levels also help chlorine work more effectively, saving you money and keeping your pool clean.
