How to Raise Alkalinity in a Hot Tub
Hot tubs are a great way to relax, rejuvenate, and relieve stress. But if the alkalinity level in your hot tub is too low, it can cause problems such as skin irritation, eye irritation, and corrosion of the hot tub equipment.
Alkalinity is a measure of the amount of dissolved alkaline substances in water. It is expressed in parts per million (ppm) of calcium carbonate (CaCO3). The ideal alkalinity range for a hot tub is between 80 and 120 ppm.
There are a few different ways to raise alkalinity in a hot tub. One way is to add baking soda (sodium bicarbonate). Baking soda is a common household product that can be found at most grocery stores. To raise alkalinity by 10 ppm, add 1.5 pounds of baking soda to the hot tub water.
Another way to raise alkalinity is to add sodium carbonate (soda ash). Soda ash is a more concentrated form of baking soda, so it is more effective at raising alkalinity. To raise alkalinity by 10 ppm, add 0.75 pounds of soda ash to the hot tub water.
If you are not sure how much alkalinity to add to your hot tub, it is best to test the water first. You can purchase a hot tub test kit at most pool and spa supply stores. Once you know the alkalinity level of your hot tub water, you can add the appropriate amount of baking soda or soda ash.
It is important to raise alkalinity slowly. Adding too much baking soda or soda ash can cause the alkalinity level to become too high, which can also cause problems. If you are unsure how much to add, it is best to start with a small amount and then test the water again.
Tips for Raising Alkalinity in a Hot Tub
- Use baking soda or soda ash. Baking soda and soda ash are the two most common chemicals used to raise alkalinity in hot tubs. Baking soda is less concentrated than soda ash, so it is a good option if you want to raise alkalinity slowly. Soda ash is more concentrated, so it is a good option if you need to raise alkalinity quickly.
- Add the chemicals slowly. Adding too much baking soda or soda ash can cause the alkalinity level to become too high, which can also cause problems. It is best to start with a small amount and then test the water again.
- Test the water regularly. The alkalinity level of your hot tub water can change over time, so it is important to test the water regularly. This will help you to ensure that the alkalinity level is always in the ideal range.
