[APD] Gauging CO2 by bubble rate

So Steve, (or anyone else who may know) do you know of any documentation that cross-references bubble rates with CO2 concentration in given tank sizes?  I would like to set a bubble rate in my 65 that will maintain the recommended 25-30ppm.  This is critical for me right now.  Something is buffering my pH down .9 points on a 65g tank, and the tank is new, so I have no way to figure how much CO2 is in solution.
