How to Raise Alkalinity in Hot Tub: A Comprehensive Guide
Method 1: Test Your Water
Before adjusting the alkalinity in your hot tub, you need to know where it stands. Test strips or a liquid test kit can help you determine the current alkalinity levels in your water. The ideal range for alkalinity is between 80 and 120 parts per million (ppm). If your levels are below this range, it’s time to start adjusting.
Method 2: Baking Soda
One of the easiest ways to raise alkalinity levels is by using baking soda. It’s inexpensive and readily available in most homes. To use, add 1.5 pounds of baking soda for every 10,000 gallons of water in your hot tub. Make sure the hot tub jets are on, and wait for 2-4 hours before retesting the water. Repeat the process if necessary to reach the desired alkalinity range.
Method 3: Alkalinity Increaser
If you prefer a more straightforward solution, you can use an alkalinity increaser. These products are specifically designed for hot tubs and are available at most pool and spa stores. The instructions will vary depending on the brand and size of your hot tub, so make sure to read the label before using it. Generally, you must add the product to the water while the jets are on and wait for several hours before retesting.
Method 4: Sodium Bicarbonate
Sodium bicarbonate is a highly effective alkalinity booster, but it is more potent than baking soda. It’s important to follow the instructions precisely and avoid over-dosing your hot tub. As a general rule of thumb, add one tablespoon of sodium bicarbonate per 100 gallons of water and wait for 2-4 hours before retesting. If your alkalinity levels need further adjustment, repeat this process.
Method 5: Hire a Professional
If you are unsure about adjusting the alkalinity in your hot tub or if you’ve tried adjusting it yourself and haven’t seen any improvement, it may be time to consult with a professional.

Method 7: Keep an Eye on pH Levels
Alkalinity and pH levels go hand in hand, so it’s essential to monitor both. If your hot tub’s pH level is too low, it can cause the alkalinity to decrease as well. You can use a basic or acidic product to adjust the pH level, depending on which direction it needs to be adjusted. Make sure to regularly test and balance both alkalinity and pH levels in your hot tub for optimal water quality.
By following these methods, you can easily raise the alkalinity in your hot tub and enjoy a clean, balanced spa experience. Remember to always follow safety precautions when handling chemicals and consult with a professional if you are unsure or need further assistance.
Maintaining proper alkalinity levels is crucial for the longevity of your hot tub and the health of those who use it. So, keep an eye on your water’s alkalinity and make adjustments as needed to ensure a relaxing and enjoyable soak every time.
5 Considerations Things When You Need to Raise Alkalinity in Hot Tub
1. Test the Alkalinity Level
The first step to raising the alkalinity in a hot tub is to test the current alkalinity level. This can be done using a test strip or a digital testing device. The ideal range for alkalinity is between 80-120 ppm (parts per million). If the alkalinity level is below this range, it must be raised.
2. Adjust pH Levels
Before adding any chemicals to raise the alkalinity, it is important to ensure the pH levels are within the ideal range of 7.4-7.6. If they are not, then they should be adjusted first using a pH increaser or decreaser before attempting to raise the alkalinity level.
3. Add Alkaline Chemicals
Once you have confirmed that both the pH and alkalinity levels are outside of their ideal ranges, you can begin adding chemicals to raise the alkalinity level. Sodium bicarbonate, also known as baking soda, is one of the most common chemicals used for this purpose and can be added directly to your hot tub water with a measuring cup or spoon.
4. Shock Treatments
If you need to increase your hot tub’s alkalinity quickly, then you may want to consider using shock treatments instead of sodium bicarbonate or other chemical treatments. Shock treatments contain chlorine or other sanitizing agents, which help raise the total alkalinity quickly while also killing any bacteria or algae present in your hot tub water.
5. Monitor Progress Regularly
Once you have added chemicals or shock treatments to your hot tub water, it is important to monitor progress regularly and take action if necessary. You should check your hot tub’s total alkalinity every few days and adjust accordingly until it reaches its ideal range of 80-120 ppm (parts per million).
5 Benefits of Raise Alkalinity in Hot Tubs
1. Improved Water Quality
Raising the alkalinity of a hot tub can help to improve the overall water quality. Alkalinity helps to buffer changes in pH, which helps to prevent drastic swings in pH that can cause damage to the hot tub and skin irritation for bathers. Additionally, raising alkalinity can help to reduce the amount of chlorine needed to maintain proper sanitization levels.
2. Reduced Corrosion
Raising the alkalinity of a hot tub can also help to reduce corrosion caused by low pH levels. When pH levels are too low, metals such as copper and iron can be released into the water, which can cause staining and discoloration on surfaces such as tile and fiberglass. Raising alkalinity helps to prevent this from occurring by keeping pH levels stable.
3. Reduced Foaming
High alkalinity levels can also help to reduce foaming in a hot tub. Foaming is caused when oils and other organic compounds interact with air bubbles in the water, creating a soapy foam that sticks to surfaces and makes it difficult for bathers to see underwater or enjoy their soak. Raising alkalinity helps to keep these oils suspended in the water, preventing them from forming foam on the water’s surface.
4. Easier Maintenance
Raising alkalinity also makes it easier for hot tub owners to maintain their spa’s cleanliness and clarity without having to constantly adjust their chemical balance or use additional products like clarifiers or enzyme treatments. The higher level of buffering provided by higher alkaline levels allows for more consistent maintenance over time without making frequent adjustments due to changes in pH or chlorine levels.
5. Improved Skin Health
Finally, raising alkalinity in a hot tub can help improve skin health for bathers by providing a more balanced environment for skin cells and reducing irritation from chlorine or other chemicals used in spa maintenance products. Higher alkaline levels also provide an ideal environment for beneficial bacteria that help keep skin healthy and free from infection or irritation caused by poor sanitization practices.
