First thing i quess you need to know is what is your tap water ph and hardness? Many councils will adjust tap water to neutral ph this is to avoid pipe corrosion using co2 however it is usually a temp ph adjustment and in many cases alters drastically once ut has been in your tank a while. once you determine this ph you can look at buffering measures.
