So much has changed from my start in the mid 60'a with a fish bowl, a couple of Comets and clump of Elodea. At that point I never imagined such things as our tanks of today. Back in those days, your source of knowledge was hanging out at the local shop on Saturday's listening in on any conversations you could. Nowadays it is so easy to find and share things on forums such as this. That's the amazing progress that I really enjoy. Thanks to you all for contributing..
