Alkalinity Increase Calculator

Formula

The formula to calculate the amount of sodium bicarbonate needed to increase alkalinity is:

$\text{AI} = \frac{\text{PV} \times \text{DI}}{1.5}$

Where:

$\text{AI}$ is the amount of sodium bicarbonate needed (pounds)
$\text{PV}$ is the pool volume (gallons)
$\text{DI}$ is the desired alkalinity increase (ppm)

What is Alkalinity Increase?

Alkalinity increase refers to the process of raising the total alkalinity of pool water to the appropriate level, which is typically between 80-120 ppm. Total alkalinity is a measure of the water’s ability to neutralize acids and maintain a stable pH level. Increasing the alkalinity of pool water is important for preventing fluctuations in pH and maintaining a healthy swimming environment.

Example Calculation 1

Let's assume the following values:

Pool Volume = 10,000 gallons
Desired Alkalinity Increase = 20 ppm

Using the formula:

$\text{AI} = \frac{10,000 \times 20}{1.5} = \frac{200,000}{1.5} = 133,333.33 \, \text{pounds}$

The amount of sodium bicarbonate needed is 133,333.33 pounds.

Example Calculation 2

Let's assume the following values:

Pool Volume = 5,000 gallons
Desired Alkalinity Increase = 15 ppm

Using the formula:

$\text{AI} = \frac{5,000 \times 15}{1.5} = \frac{75,000}{1.5} = 50,000 \, \text{pounds}$

The amount of sodium bicarbonate needed is 50,000 pounds.
