whats the formula for hardness?

DarkSoul · Apr 28, 2007

general hardness... or overall hardness or something.

I remember reading something about GH-KH=Overall hardness... or vice versa.

Anyone know for sure?

General hardness (GH)
Buffering Capacity or Carbonate Hardness (KH, Alkalinity)

Here is a link with some good info on both and then some.

Permenant hardness is what I was looking for.

I look in my fresh lab deluxe hardness test kit instructions and found

"Permenant Hardness = GH-KH"
