Earlier today I could not find my new royal gramma and assumed they had somehow died. I went to an LFS today and was telling them about it, and they claimed that my 0ppm nitrate levels may have been the cause...that a sudden change in nitrate levels (from 5-15ppm to 0ppm) could kill fish. I have since found the fish alive and well, but I am still curious...could a sudden change in nitrate levels be lethal to fish or other organisms in our saltwater aquariums? I strongly doubt it, I just want your thoughts. Thanks
