I'm no expert myself... but I don't believe CO2 will affect the hardness of water. It will, however, lower the pH.

Ok thanks mate.... any ideas how it actually does lower the pH? I have a general hardness of 13.5 and really need to soften the water!

CO2 lowers the pH because it is acidic. If you have hard water though it will not lower the pH very much. I least not much before the CO2 level poses a risk to the fish. Only way to really soften water is to use a RO/tap mix.
