Hi Dave
I use well water for my tanks. My PH is around 6.4 and I have soft water. I guess it depends on what part of the country you are from. You still have to cycle your tank tho, as using well water or city water will not make a difference in that regard. Some folks with well water do not bother using products such as Prime, since they have no ammonia or chlorine to worry about. Which basically means my using Prime with every water change is uselss. BUT I still use it anyway. It doesnt hurt.
I would suggest you use your test kit and take a reading of your water out of the tap and see what you have. From there you can decide which fish work best for you.
Good luck with your new tank.. and welcome to fishlore!

have to EDIT this so as not to confuse anyone.
When I say that the well water does not have any ammonia or chlorine and the tank doesnt necessarily needs Prime, what I mean is ... the
initial tank set up , when you first start adding water, you really do not need to add Prime especially when its used as a dechlorinator.
