What Is Kh?

[matchstickman47]

its the only parameter i cant test for
dont bother asking what test i have....not a clue
just wanted to know what it is and what affect it has on the ph of water

the KH is the buffering capacity of the water a low KH means you can have PH fluctuations if you run CO2 etc
