    If you have a bogwood, or peat in the tank, which release tannins into the water column, together with CO2 injection, would that skew the CO2 calculations, as per CO2=3*KH*10^(7-pH) formula?

    Test the tap without the tannins and do routine water changes and you can assume any difference in a tap vs a tank sample is due to the tannins.

    So tap after sitting for 24 hrs = 7.5 pH and the tankw ater after sitting for 24 hrs = 7.2, you assume that the tap water is correct and adjust and scale it down.

    IME, wood does not influence CO2 levels a great deal.

    Lumber is for the stand, not the scape.
