How to Raise pH in a Hot Tub Naturally
Balancing the pH in your hot tub is important for keeping the water safe and comfortable. If you prefer natural methods, there are ways to raise the pH without relying on harsh chemicals. Here’s how you can do it effectively.
Raising pH Without Affecting Alkalinity
One challenge when raising pH is doing so without significantly increasing the alkalinity. Alkalinity acts as a buffer for pH, so changes to one often affect the other. However, there are specific methods that can help you adjust the pH while keeping alkalinity stable. Baking soda, for example, can be used carefully to focus on pH adjustment.
How Much Baking Soda to Raise pH in a Hot Tub?
Baking soda, or sodium bicarbonate, is a common household item that can be used to raise the pH in your hot tub. Generally, adding 1.5 ounces (about 3 tablespoons) of baking soda per 500 gallons of water will raise the pH slightly. The exact amount you need will depend on how low the pH is and the size of your hot tub.
Step-by-Step Guide to Adding Baking Soda
- Test the Water: Use test strips to determine the current pH and alkalinity levels.
- Measure the Baking Soda: Based on your test results, measure the appropriate amount of baking soda.
- Turn on the Jets: Activate the jets to circulate the water, which will help the baking soda dissolve evenly.
- Add the Baking Soda: Slowly add the baking soda to the hot tub, sprinkling it over the water’s surface.
- Wait and Retest: Let the water circulate for a few hours, then retest the pH level. Repeat if necessary until you reach the desired pH.
Using Soda Ash to Increase pH
Step-by-Step Guide to Adding Soda Ash
- Test the Water: Begin by testing your hot tub water to check the current pH level.
- Measure the Soda Ash: Calculate the amount of soda ash (sodium carbonate) needed. A common guideline is to add 1 ounce of soda ash per 500 gallons of water to raise the pH by 0.1.
- Turn on the Jets: Ensure the water is circulating by turning on the jets.
- Add the Soda Ash: Gradually add the soda ash to the water, distributing it evenly.
- Wait and Retest: Allow the water to circulate for several hours, then test the pH again. Adjust if needed.
Other Natural Alternatives to Raise pH
In addition to baking soda and soda ash, there are other natural methods to raise pH levels. Some hot tub owners use products like borax, which is less likely to affect alkalinity but still raises pH. Always start with small amounts and test frequently to ensure you achieve the right balance without overcorrecting.
