Check and make sure your tests aren't expired. The last 4 numbers of the lot number are the exp date. For instance if the lot ends in 1109 the test expired in Nov. 2009.
A 2 gallon with one fish should start to show ammonia quickly.. maybe not in the first few days but definitely by the end of the week. Don't do a water change until you get an ammonia reading. When you get a reading do a 10-20% change.
Sorry to steal this thread from the OP.
I don't know what its exp date is I will have to look at that soon.
I did think my ammonia test was "broken" So I did my own little experiment. I added a drop of window cleaner (with ammonia) to the test tube which just had tap in it. The test immediately turned bright orange (5+ppm). So I know the test is working fine.
When I test my Bettas water I get a very very feint yellow, which is way below the orangish .25 ppm the test color is.
