Get pH and KH, forget the CO2 one. I don't think that that
measurement will ever be much good. (I've explained why before.)
Even the pH measurement must be quick, if a sample is taken from the
aquarium, because the CO2 leaves the solution and the pH changes.
A pH probe _in_ the aquarium is much better.
