What Does Soda Ash Do to pH

Soda ash can do just that. Also known as sodium carbonate, it raises both the pH level and total alkalinity of the pool when added to the water. Note: The ideal pH level for a pool is between 7.4 and 7.6. Anything over this number and the water is too alkaline (or basic), while anything under is too acidic.

How does soda ash affect pH?

Soda ash raises pH and alkalinity. Usually, if you try to use it to raise pH, you will raise the alkalinity too high and have to add acid to adjust it back down.

How much soda ash do I add to raise pH?

To raise the pH of your pool, fill a 5 gallon bucket with water. Then, add 6 ounces of soda ash to the bucket for every 10,000 gallons of water in the pool. Pour that mixture around the pool’s perimeter while the filter is running so it mixes evenly. After an hour, check the pools pH.
