I'm new here, and I need help setting up my first tank. first of all I need to determine the pH and hardness of the water right? So, I went and looked at a chart with all the numbers... What I got from it is this- the hardness is 125 ppm, what is that in dH? (General hardness, whatever that abbreviation is, the most common one I've seen is dH so I'm using that one, correct me if I'm wrong.) and the pH ranges from 7.7 to 8.2. I'd rather not have to mess with the levels too much, so what fish can I have in those conditions that are easy to care for? Ideally I would want fish that could be kept in a 10 gal. tank. Thanks for all your help!
