I'm loving my API test kit but I have to ask -
When I test for ammonia now, all three of my habitats (the turtle tank, the aquarium, and the impromptu goldfish rescue tub) I get this color which looks almost completely yellow (o ppm) but I can't honestly say I don't detect just a hint of green.
It's weird to think of color gradients in such quantitative terms, and I wonder how much of a margin for error should I be giving? If I had to put a number to the color, I would say 0.1 - 0.05 ppm.
But I'm trying to be really good about this and I understand I'm not supposed to have fish in anything above 0.00 ppm.
Am I being too uptight or should I keep working/waiting for the ammonia?
ps - nitrite/nitrate levels are a totally different story - I'm just asking about ammonia here (although I guess the question would also apply to a barely discernible reading for nitrite...)
