Hello, I live in NE Knox County just outside Knoxville. I seem to make every beginner mistake you can make so I am prob of no help to you. But, I do have questions for you if you don't mind. Mainly, I am wanting to get a pair of GBR's and was excited to see The Aquarium on Papermill has some acclaimated to their well water which they said has a ph of about 7.4 they didn't say about gh or kh. I use water from NE Knox Utility and my ph is 7.8 but what really concerns me is that (if I am reading the test kit correctly) my gh is 220 ppm. The folks at the Aquarium have told me before that is extremely high and what little I know about the GBR's I believe they won't do well in the hard water. What water are you using & is it hard? Thanks in advance, & happy to meet you!
