Water value

[wt1961]

My tap water GH = 12 I need to now for this GH value and when
KH = 12 PH = ? (How match PH must be)
KH = 11 PH = ? (How match PH must be)
KH = 10 PH = ? (How match PH must be)
KH = 9 PH = ? (How match PH must be)
KH = 8 PH = ? (How match PH must be)
KH = 6 PH = ? (How match PH must be)
KH = 5 PH = ? (How match PH must be)
KH = 4 PH = ? (How match PH must be)
KH = 3 PH = ? (How match PH must be)
KH = 2 PH = ? (How match PH must be)

Thanks.

There is no direct relationship. Carbonate hardness just measures the buffering capacity of your water. PH can be high or low. However, the greater buffering capacity you have, the less likely you are to have a quick, major change in pH.

I hope this helps.
