In today’s episode of Poolside Chat, Rob and Matt tackle another common swimming pool question:
- What is the difference between alkalinity and baking soda?
Alkalinity or total alkalinity is really the measurement of all the bicarbonate, carbonates, and hydroxides in the water. Proper alkalinity levels prevent issues like corrosion, scaling, and eye irritation. An ideal range of alkalinity is 80 to 100 parts per million. Baking soda or sodium bicarbonate is used to raise total alkalinity in the pool water. Total alkalinity is the measurement, and baking soda is the substance used to raise alkalinity.
Is there a difference between alkalinity sold in the pool stores and baking soda found on grocery store shelves?
No, they’re both sodium bicarbonate. The only difference would be that a pool supplier typically offers larger quantities like 25 to 50 pounds.
