| || | Not when doing fishless. Water changes remove the ammonia and nitrites needed by the bacteria which could finally have been converted to nitrates. Do a large water change only when you finally see the results as undetectable level of ammonia and nitrites with nitrate level probably in excess to dangerous levels. A large water change will dilute the excess nitrates. Nitrates should not exceed 40 ppm which is toxic to the fish.

Don't fiddle with the pH. Your pH is fine for guppies. Fiddling with it is asking for troubles.
I've read somewhere that guppies prefer a ph level of something between 7.0 and 7.5
