Hi Folks,
I want to try to gauge the acccuracy of the pH, KH, CO2 chart for determining CO2 concentration in the typical (!) tropical planted aquarium with fish. As I understand it, this chart relies on carbonic acid being the only acid determining the pH of the aquarium water. But there are other acids to consider, one of which is humic acid.
So, in practice, just how accurate are the CO2 figures that it indicates?
