The GH (general hardness) is important to fish, even more than pH. You can get this from your municipal water supply people, they probably have a website; if you can't fathom it, post the link and I can take a look. The KH is less important as it does not affect fish at all, but it does serve to "buffer" the pH, so this (the KH which is carbonate hardness, or Alkalinity) is worth knowing as it will tell us if the pH may lower or not.
