WebbThanks to Henry's Law, we know that CO 2 will off-gas until it reaches equilibrium with the air above the pool. That point of equilibrium is basically a limit, or a ceiling. Since pH rises as CO 2 leaves the water, we call this the pH ceiling of a swimming pool. And yes, pH can absolutely rise above this ceiling, but not naturally.
