Tonight, my wife and I did a 25% water change, as we do weekly. About an hour later, we noticed that six of our eight Buenos Aires tetras were dead. Another is swimming around the top of the tank. The two Bolivian rams seem fine.
We realized that we forgot to add Prime after the change. I assume the chlorine killed them that quickly?
