I have had a 20gal set up for 6 months now and I always get an ammonia reading with a greenish tinge (looks to be between 0 and 0.25ppm on the chart)
I also have a Mardel in tank liveNH3 metter which stays consistently at yellow (0 ammonia).
I tried running a control sample with DI water to see what color it come out and it came out with a greenish tinge again. I did use the same test tube I always use but I rinsed it out several times in DI water. Also, I am on my second ammonia kit now and both this one and the previous one gave me the same <0.25ppm readings.
I see the yellow color for maybe the first 3mins of the test, but then I see the greenish appear in both the DI water and my tank water.
So my questions are:
-What does your API ammonia liquid test kit 0ppm look like?
-I feel tempted to assume I am getting 0 readings despite of the greenish tinge,does seem reasonable?
On a side note: I test my water every day and my fish are looking great, so I am not worried about my fish but it has been nagging me that I don't get a "clear" 0ppm ammonia reading
Thanks for any help
