As long as you restrict the dropchecker's sample water to 4 dkH as suggested in the article the content of the tank water is completely irrelevant. Now, you should not be using any buffers at all as these are pointless. Neither fauna nor fauna care about the pH of the tank water so using buffers is a complete waste of time and energy. Having said that however, the whole purpose of the dropchecker is to isolate the measurement sample from the tank water. The buffers added to the tank water cannot easily find their way into the dropchecker water sample. Only CO2 and other gasses evaporate from the tank water into the air cavity inside the checker and then down from that air cavity into the sample water. Therefore there is no need to worry about the composition of the tank water. As long as you do not add buffers to the dropchecker itself you have no problem.
