    I have a API test kit and it is measuring the KH in hundreds. Mine is measuring around 180. When i look at the CO2 charts all over the internet all kh values are from 0 to 20. Am i missing something here?

    Thanks

    Well for one are you using api liquid test? Also what type of measurement are you using (drops?)

    Did you mix up the GH and KH?

    Because in charts, KH is expressed in degrees of Karbonate hardness: 1 dKH=17.9 ppm KH=1 drop API test.
    Your KH of 180ppm is 10 dKH

    The API test has both dKH and ppm. dKH is the German measurement if I remember correctly, and a lot of people use that scale for both KH and GH.
