I'm about to do my first water change after 7 days and am concerned about the PH. We filled the tank with Poland Spring which has a PH of 8. I'm assuming distilled water has a PH of 7... Is that right? And the other thing I assumed about distilled is that it is tripped of all trace elements and nutrients... Is that true? And if so, do I need to dose the changed water with everything or wait till it gets in the tank, test then dose.
