API ammonia color?

    I feel incredibly dumb but I cannot figure out if the ammonia reading is 0 or 0.25 ppm. It's not yellow but not quite greenish either. It's this yellow with a baby touch of green?? I want to do a water change if it's .25 but I really can't tell! If it were 0 would it be truly a clear yellow? I've got a 0 nitrite reading and 15-20 nitrate reading.

    Yes, 0 will actually be an obvious yellow (assuming that you don't have any issues seeing colors). If it's not green enough to be .25, it's probably like .1 or .15

    I hightly suggest to look at the colors againt a white light (makes it easier to read)

    With it reading that low, I wouldn't worry about doing a water change at this point. Depending on water temp and pH, some of that ammonia is actually non toxic ammonium, so the amount of ammonia that your fish may be exposed to would be very small.
