Thanks, that makes the readings make sense. However, I read on this forum that the KH/PH calculation for CO2 is invalid if you have any kind of buffering in the water. I would think that most substrates and/or rocks or driftwood would tend to buffer the water to some degree, making the calculation ineffective. Is that the case, or is it not enough to be significant.
