WebIn the first simulation, the initial water is groundwater in equilibrium with calcite at a partial pressure of carbon dioxide of 10-1.5 [log P(CO 2) = -1.5]. Pure water is defined with the SOLUTION data block with default values for pH (7.0), pe (4.0), and temperature (25 °C); calcite and carbon dioxide, which dissolve to equilibrium, are ... WebThe amount of carbon dioxide in water determines the pH of the water. The more CO 2, the lower the pH, and vice versa. A pool's pH will naturally rise over time, thanks to CO 2 leaving the water. This is natural, and you are doing nothing wrong. Orenda Products.
