I never ran mine with a peristaltic pump; I suppose a dosing calculation is possible at a given and constant reactor pH but would require a measure of the actual concentration on alk and calcium in the effluent as a starting point; I think. The concentration of alk and calcium in the effluent is governed by the pH in the reactor; lower equals more dissolution of the calcium carbonate ad vis versa. Balancing the flow through the reactor and the CO2 injection is how most tune in the alk/calcium .
