I don't know, i just retested the tank 4 times, with different test bottles and two said about 30-40ppm while the other two said about 20-30ppm, while this morning it was 0 all 4 times. I have the API freshwater test kit, but the biggest thing i hate about it is the 10 and 20ppm for nitrate look the same, as does the 40 and 80. So when it is that color i guess you assume its between them, but i like knowing exactly.
