George gave a very good explanantion of why Ammano's CO2 readings
might vary with his KH/pH/CO2 table readings. But he did not say
that you _need_ to be that accurate.<g>
IMO, it is important to use _good_ KH and pH test kits. Then use
a table that has good definition. While this may not give you
pinpoint accuracy, that is not terribly important. If all three
parameters are within reasonable limits, you're all set.
