    Please excuse if this is stupid ? my tank is set up with a kh of 2 to 2.5 degrees over a week period between water changes. does it matter if my drop check is using a standard kh solution of 4 degrees to figure out my in tank co2 levels? or should i be using a Kh standard solution of 2 degrees so i can also figure out ph? I'm a little cofused, if anyone could shed some light or point me to the write post i would be greatful.
    thanks Troy

    The drop checker's CO2 measurement is independent of the tank's KH.

    So you need not worry, a tank with 20KH or 2KH can still read the same CO2 ppm.
    The reference solution inside the drop is always the same no matter what is going on inside your tank, the air gap prevents the tank water from mixing, but still allows the CO2 gas to equilibrate between the tank and the test drop checker.
