And what does calcium do is this equation?Alkalinity and CO2 together determine pH mathematically.
CO2 has no direct impact on alkalinity.
CO2 and alk (and pH) will alter the ongoing demand for alkalinity. Higher pH and alk yield higher ongoing consumption of alk.
For example, overdosing kalk causing ph to rise higher and higher making the excess calcium to percipitate?
Is there a situation/ possibility that calcium might go in solution again as ph goes down after some time? And thus co2 rises...
