What is the required muriatic acid amount to shift pH from 7.6?

When attempting to adjust the pH of pool water, the calculation for the amount of muriatic acid needed usually depends on the current pH level and the desired pH level. Typical guidelines suggest that to lower pH from 7.6 to a more desirable level, it is necessary to use a specific quantity of muriatic acid.

In many cases, around 12 oz of muriatic acid is recommended to decrease pH in a standard-sized pool (usually around 10,000 gallons) by about 0.2 units. This is based on standard industry practices, which consider factors such as the pool's volume, current alkalinity, and the specific pH adjustment required.

Choosing 12 ounces aligns with these common practices, making it the appropriate volume to alter the pH level effectively without overshooting the target. This amount is often seen as a safe starting point for many standard adjustment tasks in pool maintenance.
