I've read people saying that ammonia levels at or above 0.25 ppm (mg/L) are dangerous for fish. My Nutrafin test kit's first readable level is 0.6 mg/L, and it says that anything under 1.2 mg/L is safe when using Nutrafin Cycle Biological Aquarium Supplement. From what I've read it is unlikely products of this nature will do much good (though I could be wrong).
Should I start using a different test? If so, what are some of the more popular (and therefor hopeful more accurate) ones?
