Congrats on the new tank(s).
The ecology of a tank will cause fluctuations in pH levels.
For example, a well maintained tank with low bioload and weekly 25% PWC’s, gravel vacuuming and filter maintenance will have a much more consistent pH and water parameter levels.
A heavily stocked tank with excess detritus in the gravel and a heavy buildup of mulm in the filters will cause all of the bacteria (good and bad) to utilize trace elements and minerals a lot faster and they put out CO2 as part of their living so that will cause the pH to come down much faster as the KH levels decrease.
Driftwood and live plants can cause the pH to get lower/higher also.
If the KH gets too low, the nitrifying bacteria can start to die off and/or the pH can crash to a deadly low level.
