How Much Sodium Bisulfate to Lower Alkalinity in Your Pool

Maintaining proper water chemistry in your swimming pool is essential for a safe and enjoyable swimming experience. One key component of this chemistry is alkalinity, which helps stabilize pH levels. If your pool's total alkalinity is too high—typically above 120 parts per million (ppm)—you may find that pH fluctuations become more pronounced, leading to potential issues with water clarity and swimmer comfort. Sodium bisulfate, commonly known as dry acid, is an effective product for lowering alkalinity.

Determining how much sodium bisulfate to use to lower alkalinity involves a few straightforward steps. First, you’ll need to measure the current alkalinity level, which can be done using a test kit or test strips specifically designed for pools. Once you have your reading, you can compare it against your desired level, usually between 80 and 120 ppm for most residential pools.

As a general rule of thumb, adding one pound of sodium bisulfate will lower the alkalinity of 10,000 gallons of pool water by approximately 10 ppm. Therefore, if your pool contains 20,000 gallons and your test shows an alkalinity of 150 ppm, you would need to lower it to around 100 ppm. To calculate the amount needed, you first figure out the difference 150 ppm - 100 ppm = 50 ppm. Knowing that one pound reduces alkalinity by 10 ppm for 10,000 gallons, you would need to add 5 pounds of sodium bisulfate to your pool.

To apply sodium bisulfate, it’s best to distribute it evenly around the perimeter of the pool while the pump is running. This ensures that the chemical dissolves properly and disperses throughout the water. Additionally, avoid adding the chemical directly into the skimmer or filter system, as this could lead to damage.

After adding sodium bisulfate, allow the water to circulate for several hours, then retest the alkalinity level to confirm the new reading. It’s important to make adjustments gradually, as changing alkalinity or pH too quickly can lead to water balance issues. If after retesting the measurement is still above your target range, you can repeat the process.

In summary, maintaining optimal alkalinity is crucial for pool care, and sodium bisulfate offers a straightforward way to lower it. By calculating the correct dosage and applying it properly, you can enjoy a more balanced and welcoming swim environment.
