I don't think Roger and I have any trouble. I'm trying to hone in on something and Roger is being kind enough to help me, which he graciously has done many times in the past. My interpretation is that with higher KH it takes more CO2 to maintain the lower pH values. CO2 lowers pH and KH raises it. That's the only relationship of note. With high KH you can have a higher CO2 level and stay within a given pH range because the higher KH keeps the CO2 form pushing the pH too low, it counteracts the effect on pH, it buffers. So in that sense, a high KH allows more CO2, but you have to put it in yourself, so to speak ;-) Scott H. --- Amit Brucker <amitb@gtek.co.il> wrote: > Oh I didn't mean to cause any trouble....
