Maintaining the proper pH balance is crucial for maximizing the enjoyment and longevity of your hot tub. The addition of baking soda is a well-known method for raising the pH of hot tub water, but determining the appropriate amount can be a bit tricky. This comprehensive guide will help you understand how to measure pH, calculate the required amount of baking soda, and safely adjust the pH of your hot tub water.

Defining pH and Its Importance
pH is a measure of the acidity or alkalinity of a substance. It ranges from 0 to 14, with 0 being the most acidic, 14 the most alkaline, and 7 neutral. For hot tubs, a pH range between 7.2 and 7.8 is ideal to prevent corrosion of equipment, minimize skin irritation, and ensure proper sanitizer effectiveness. When the pH drops below this range, the water becomes acidic and can cause uncomfortable skin sensations and damage the hot tub’s components. Using baking soda can effectively neutralize the acidity and raise the pH back to the optimal range.
Testing and Calculating the Required Amount of Baking Soda
Before adding any baking soda, it’s important to measure the current pH of your hot tub water using a pH test kit. Once you have an accurate pH reading, you can determine the amount of baking soda needed to raise it to the desired 7.2-7.8 range. The general rule of thumb is 1 pound of baking soda per 10,000 gallons of water will increase the pH by about 1 unit. As an example, if your hot tub holds 500 gallons of water and the pH is currently 6.8, you would need to add:
Required Baking Soda = 1 pound x 500 gallons / 10,000 gallons x 1 pH unit
= 0.05 pounds or approximately 2.2 ounces of baking soda
Step-by-Step Guide to Adding Baking Soda
-
Dissolve Baking Soda: Dissolve the calculated amount of baking soda in a bucket of warm water before adding it to the hot tub. This helps it dissolve evenly and prevents it from caking up at the bottom.
-
Circulate Water: Turn on the jets or circulation pump to ensure the baking soda solution gets distributed evenly throughout the hot tub water.
-
Retest pH: Use the test kit to remeasure the pH after 15-30 minutes. If needed, make incremental adjustments by adding small amounts of dissolved baking soda and retesting until the pH reaches the desired level.
-
Adjust Other Chemicals: After raising the pH, you may need to adjust the levels of other chemicals, such as chlorine or bromine, to maintain proper sanitization. Check manufacturer instructions for recommended levels.

Safety Precautions
When handling baking soda, it’s important to take precautions to avoid inhalation and skin irritation:
- Wear a dust mask.
- Avoid breathing in the powder.
- Wear gloves to prevent skin contact.
- Rinse off any baking soda that gets on the skin.
If you experience any difficulty breathing or skin irritation while handling baking soda, seek medical attention immediately.
