I have kept fish all my life, and we have to put stuff in the water that keeps the chlorine in tap water from poisoning the fish. On the bottle, it says it also eliminates nitrate and nitrite, which are bad for fish. Well, I thought these were the same thing as nitrogen, so when I found out that a huge percent of our air is nitrogen, I was terrified, because I thought, That's the stuff that kills fish!
