   Thanks to numerous questions from listeners (to [email protected]), Eric explains the actual chemistry of why alkalinity rises in pools feeding CO2 for pH management. CO2 itself does not raise alkalinity. Eric shows what's really going on, and what a pool operator can do about this constant rise in total alkalinity.
