what is your carbon hardness and general hardness in that tank? and how offen are you doing water changes and how much of the water are you changing?
Carbonate hardness (KH) measure bicarbonate(HCO3-) and carbonate(C03).. this is the Agent that helps to stable PH. when doing water changes you help balance the carbon hardness and general hardness.
a way of getting the ph down, would to be use ro/di and some ph buffer.
you could also age the water for 24 with some peat moss..
what fish do you have in the tank, and where are you getting them from.
