I agree with Invert. Most times, you don't want to mess with the pH. It will constantly have to be adjusted, and if you have a high buffer, everytime you adjust the pH it's gonna creep back to where it was. Any slight change in pH will stress the fish out more and do more harm than good. The tetras will be perfectly happy in the water you have now, assuming you clean the tank every week. :)
