I dont recall where I saw it, but IIRC, the use of peat filtration and/or Blackwater Extract affects the standard calculation of CO2 concentration, which can normally be obtained if pH and KH are known. I am converting a 29 gal to a blackwater biotope, and am going to use Kent Black Water Expert to achieve the proper conditions.

Is there an easy way to calculate CO2 concentrations when the additive is used, or do I need a CO2 test kit?
