Question: what is the difference between baking soda and alkalinity increaser?
Answer: Using sodium bicarbonate will have a more measurable effect on total alkalinity, while only raising the pH of water slightly. ... On the other hand, 12.2 ounces of sodium carbonate will raise the pH of 10,000 gallons of water by 0.4, as well as increase the total alkalinity by roughly 8.6 ppm.
