About this episode

Eric explains the chemistry behind the rise of alkalinity in pools when using CO2 for pH management.

Thanks to numerous questions from listeners (to ruleyourpool@gmail.com), 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.
