Baking Soda Alkalinity Calculator

Stop pH bounce and stabilize your water. Calculate exactly how much sodium bicarbonate (baking soda) is needed to lock in your pH levels.

Quick Conclusion
To raise Total Alkalinity (TA) by 10 ppm in a 10,000-gallon pool, you need 1.5 lbs of ordinary baking soda. Maintain TA between 60-120 ppm depending on your sanitizer type.

Technical Comparison

Sanitizer Type Ideal TA Range Chemical Priority
Liquid Chlorine / Salt 60 - 80 ppm Slows pH Rise
Trichlor Pucks 100 - 120 ppm Buffers Acidic Pucks
Bromine 100 - 120 ppm Standard Buffer
