Sodium bisulfate, also known as dry acid, is a popular choice for lowering pH and alkalinity in swimming pools. It’s easy to use and relatively inexpensive, making it a go-to option for many pool owners.
But with so many products on the market, it can be tricky to know which sodium bisulfate is best for your pool. In this guide, we’ll break down everything you need to know about sodium bisulfate and help you choose the right product for your needs. Let’s get started.
What Is Sodium Bisulfate?
Sodium bisulfite is a chemical compound with the formula NaHSO4. It is a white solid that is highly soluble in water.
It is commonly used as a pH adjuster in pools or hot tubs. When used in pools, it lowers the pH of the water, making it more acidic. This can be beneficial as it helps to prevent the growth of algae and bacteria. In hot tubs, sodium bisulfate can lower the water’s pH, making it more comfortable for people to soak in.
What is Sodium Bisulfate Used For?
Sodium bisulfate is used for various purposes, most commonly as a pH adjuster or acidifier. It can be found in many different products, including pool chemicals, cleaning products, and food additives.
When used in pools, sodium bisulfate lowers the pH level of the water, making it more acidic. This can be beneficial as it makes it harder for algae to grow and helps to keep the water clean. It can also help to prevent calcium buildup on pool surfaces.

Sodium Bisulfate Vs. Muriatic Acid
You should be aware of a few key differences between sodium bisulfate and muriatic acid before using either one to clean your pool.
- Sodium bisulfate is a dry, granular chemical that is added to water to lower the pH levels. It is often used in swimming pools that have high alkalinity levels.
- On the other hand, Muriatic acid (Hydrochloric Acid) is a liquid chemical used to lower the pH and total alkalinity levels in swimming pools. It is also used to remove calcium deposits from pool surfaces.
So, which one should you use to clean your pool?
If you have a high alkalinity level in your pool, sodium bisulfate is the better choice. It will lower the pH levels without affecting the chlorine levels. Muriatic acid is better if you need to remove calcium deposits from your pool surfaces. It will also lower the pH and total alkalinity levels in your pool.
As always, follow the manufacturer’s instructions carefully when using either one of these chemicals. And, if you have any questions, ask a professional before using either chemical in your pool.
How to Lower pH With Sodium Bisulfate?
To lower the pH of your pool with sodium bisulfate, also called dry acid, you’ll need to follow these steps:
1. Test Your Pool pH Levels
First, you need to test your pool water to see the current pH levels. You can purchase a swimming pool test kit from your local hardware store or online.
2. Add the Sodium Bisulfate
Once you know how much sodium bisulfate is needed to lower your pool’s pH, you can add it directly to the water. Be sure to do this when nobody is swimming in the pool and follow the manufacturer’s directions.
3. Let The Product Work
After adding the sodium bisulfate, you’ll need to wait for it to work. The pH levels of your pool should start to lower within a few hours.
3. Test the Pool Water Again
After you’ve added the sodium bisulfate, it’s important to test the water again to ensure that the pH levels have been lowered to where you want them. If not, you can add more sodium bisulfate until you reach the desired pH level.
Sodium bisulfate is a popular choice for lowering pH levels in pools because it’s effective and easy to use. Follow the steps above carefully to ensure that your pool water is at the perfect pH level for swimming.
How to Lower Alkalinity with Sodium Bisulfate?
Many people ask how to lower alkalinity in their pool with sodium bisulfate.
