my tank's pH was at 7.0, and then the tap water's pH lowered to 6.4 (even though my fish didnt get stressed), and then when i added driftwood the pH in my tank was lowered to 6.0, which really stressed my fish. i'd like to raise the pH to 7.0 again, if it doesn't stress my fish too much, because the tanks at my lfs mostly have a neutral pH.
could i just add a partial dosage of Proper pH?
