re: KH, pH, CO2 table ...

Tom was looking for the KH, pH, CO2 table. 
The original(?) reference is in the Optimum Aquarium by Kipper and Horst.

Here are two formulas you can stick into a spreadsheet that give you the table(s):

pH as a function of CO2 concentration and KH value:

CO2 concentraction at a given pH and KH	

for both, KH is in german degrees (standard units), CO2 in ppm, and pH in standard units.
