Could you tell us a little more about that Paul? I noticed something
similar a couple of weeks ago reading descriptions of CO2 reactors. My
interest is along the following lines: Assume a steady CO2 bubble size and
flow rate, and a steady flow of water through a given CO2 reactor. If I
have say, about 7 mg/l CO2 at a pH of 7.0 with KH of 2.5, would I have a
greater CO2 mg/l concentration if I raised the KH to say 4? In other
words, if I would be willing to accept a higher base case pH, could I
increase the CO2 levels for a given supply of CO2?
