How much sodium sesquicarbonate is necessary to increase alkalinity by 10 ppm in 10,000 gallons of water?

To increase the alkalinity by 10 parts per million (ppm) in 10,000 gallons of water, the correct amount of sodium sesquicarbonate needed is 1 1/4 lbs. This calculation is based on the chemical properties of sodium sesquicarbonate and its interaction with water.

When adding sodium sesquicarbonate to water, it acts as a buffering agent that stabilizes pH levels by increasing the total alkalinity. Each chemical compound has a defined capability to affect water chemistry, and sodium sesquicarbonate has a known dosage effect.

For this specific dosage, the empirical data used by pool operators indicates that approximately 1 1/4 lbs of sodium sesquicarbonate is required to achieve the desired increase in alkalinity for a 10,000-gallon pool. Understanding the specific dosages for water treatment and chemistry provides valuable insights into maintaining balanced and healthy pool water.

In practice, using the proper amount is essential for achieving the needed adjustments without overshooting, which could potentially lead to imbalances that affect the water quality.
