Howdy, I am trying to figure out the co2 calculator and it uses degrees of hardness gh\kh and the test kit I have shows it as parts per million, is there and easy way to convert this? Hopefully this way I can see how much co2 I have at the present. My PH is hovering right around 7.1, my KH is right around 260 ppm and my GH is nearly 90 ppm. Thnaks and looking forward to understanding what is going on in my tank.
