For your Bucepha aquarium, you must be using an inline CO2 reactor ran by a separate external canister filter (a total of two external canister filters).
Thanks for showing us the chart and the thorough description of your CO2 dosing. I admire your computerized system.
By the way, where in Poland do you live? I have a college instructor (Slawomir Wozniak) who is also a principal dancer at Teatr Wielke.
