Lowering alkalinity in your pool is a crucial step in maintaining the overall health and balance of your pool water. High alkalinity can lead to a number of problems, including cloudy water, scale buildup, and skin irritation.
There are a few different ways to lower alkalinity in pool, and the best method for you will depend on the specific circumstances of your pool. Generally, to lower alkalinity in pool by 10 ppm, you will need to add 2.5 pounds of muriatic acid or 3.5 pounds of sodium bisulfate per 10,000 gallons of pool water.
In this guide, we’ll discuss the importance of alkalinity, how to test your alkalinity, and the different methods you can use to lower alkalinity in pool.
Key takeaways:
| Method | Cost | Ease of use | Effectiveness |
|---|---|---|---|
| Muriatic acid | $10-$20 per gallon | Easy to use | Very effective |
| Sodium bisulfate | $5-$10 per pound | More difficult to use | Less effective than muriatic acid |
How to lower alkalinity in pool with muriatic acid:
- Test your pool water to determine the alkalinity level.
- Calculate the amount of muriatic acid needed to lower the alkalinity to the desired level.
- Add the muriatic acid to the pool water slowly, while stirring constantly.
- Retest the pool water to ensure that the alkalinity level has been lowered to the desired level.
How to lower alkalinity in pool with sodium bisulfate:
- Test your pool water to determine the alkalinity level.
- Calculate the amount of sodium bisulfate needed to lower the alkalinity to the desired level.
- Dissolve the sodium bisulfate in a bucket of water.
- Add the sodium bisulfate solution to the pool water slowly, while stirring constantly.
- Retest the pool water to ensure that the alkalinity level has been lowered to the desired level.
It is important to note that lowering alkalinity in pool can be a time-consuming process, and it is important to be patient. It may take several days or even weeks to lower the alkalinity to the desired level. However, by following the steps outlined in this guide, you can safely and effectively lower alkalinity in pool.
Understanding Alkalinity in Pools
Maintaining the proper alkalinity level in your pool is essential for ensuring the comfort and safety of swimmers. Alkalinity acts as a buffer against pH changes, preventing the water from becoming too acidic or basic. When alkalinity is too high, it can lead to a number of problems, including cloudy water, scale buildup, and skin irritation. Conversely, when alkalinity is too low, the water can become corrosive and damage the pool’s equipment.
- Testing: Regularly testing your pool water is the first step to managing alkalinity. Test kits are available at most pool supply stores and can be used to measure the alkalinity level in parts per million (ppm).
- Causes: High alkalinity can be caused by a number of factors, including the type of pool surface, the source of the water, and the use of certain chemicals. Understanding the causes of high alkalinity can help you prevent the problem in the future.
- Consequences: High alkalinity can have a number of negative consequences, including cloudy water, scale buildup, and skin irritation. It can also make the pool water more difficult to disinfect.
- Solutions: There are a number of different ways to lower alkalinity in pool, including using muriatic acid, sodium bisulfate, or soda ash. The best method for you will depend on the specific circumstances of your pool.
By understanding the key aspects of alkalinity in pools, you can take steps to maintain the proper alkalinity level and ensure the comfort and safety of your swimmers.
Testing
Regularly testing your pool water is the first step to managing alkalinity because it allows you to identify any potential problems early on. By testing your water regularly, you can track the alkalinity level and make adjustments as needed to keep it within the ideal range.
- Importance of Testing: Testing your pool water regularly is important because it allows you to identify any potential problems early on. By testing your water regularly, you can track the alkalinity level and make adjustments as needed to keep it within the ideal range.

Benefits of Testing: There are many benefits to testing your pool water regularly, including:
- Identify potential problems early on
- Track the alkalinity level over time
- Make adjustments as needed to keep the alkalinity level within the ideal range
- Consequences of Not Testing: If you do not test your pool water regularly, you may not be aware of any potential problems until they become more serious. This can lead to costly repairs or even health problems for swimmers.
By understanding the importance of testing your pool water regularly, you can take steps to maintain the proper alkalinity level and ensure the comfort and safety of your swimmers.
Causes
Understanding the causes of high alkalinity is important because it can help you prevent the problem in the future. By knowing what factors contribute to high alkalinity, you can take steps to avoid them or mitigate their effects.
- Pool Surface: The type of pool surface can affect the alkalinity of the water. Concrete pools tend to have higher alkalinity than vinyl or fiberglass pools. This is because concrete is a porous material that can leach calcium into the water.
- Water Source: The source of the water can also affect the alkalinity of the pool water. Well water often has higher alkalinity than city water. This is because well water contains dissolved minerals, including calcium and magnesium, which can increase the alkalinity of the water.
-
Chemical Use: The use of certain chemicals can also increase the alkalinity of the pool water. For example, adding sodium bicarbonate to the pool water can increase the alkalinity. Sodium bicarbonate is often used to raise the pH of the pool water, but it can also increase the alkalinity.
By understanding the causes of high alkalinity, you can take steps to prevent the problem in the future. For example, if you have a concrete pool, you can use a pool cover to prevent the water from evaporating and leaving behind dissolved minerals. If you have well water, you can install a water softener to remove the dissolved minerals before they enter the pool.
Consequences
High alkalinity can have a number of negative consequences for your pool. These consequences include:
- Cloudy water: High alkalinity can make your pool water cloudy. This is because the calcium carbonate that is present in the water can form a precipitate, which makes the water appear cloudy.
- Scale buildup: High alkalinity can also lead to scale buildup on the pool’s surfaces. This scale is made up of calcium carbonate and can be difficult to remove.
- Skin irritation: High alkalinity can also cause skin irritation. This is because the high pH of the water can irritate the skin.
- Difficulty disinfecting: High alkalinity can make it more difficult to disinfect the pool water. This is because the high pH of the water can make it difficult for chlorine to kill bacteria.
If you are experiencing any of these problems, it is important to lower the alkalinity of your pool water. There are a number of ways to do this, including using muriatic acid, sodium bisulfate, or soda ash. The best method for you will depend on the specific circumstances of your pool.
Solutions
There are a number of different ways to lower alkalinity in pool, and the best method for you will depend on the specific circumstances of your pool. Some of the most common methods include:
- Muriatic acid: Muriatic acid is a strong acid that can be used to lower alkalinity in pool. It is important to use muriatic acid carefully, as it can be corrosive.
- Sodium bisulfate: Sodium bisulfate is a dry acid that can be used to lower alkalinity in pool. It is less corrosive than muriatic acid, but it can be more difficult to use.
-
Soda ash: Soda ash is a base that can be used to raise alkalinity in pool. It is important to use soda ash carefully, as it can cause the pH of the water to become too high.
When choosing a method for lowering alkalinity in pool, it is important to consider the following factors:
- The size of your pool
- The alkalinity level of your pool water
- The desired alkalinity level
- Your budget
Once you have considered these factors, you can choose the best method for lowering alkalinity in pool.
