amonia testing question

[alkad mzu]

hello all,
kind of hard to explain, bare with me.
i tested for amonia and didnt empty the test tube.
when i went to empty it out a few hours later i noticed that it was now
yellow. when i test the water i wait 5 -10 minutes to see results. i use
aquarium pharm test kits. it never occured to let the test sit for
longer than the recommend time.
what does this mean?

If you don't wait long enough, you get an inaccurate reading. If you wait
too long (way too long in this case), you also get an inaccurate reading.
Just follow the instructions and you will be fine.

So, it means absolutely nothing, unless you believe in conspiracies.
Drinking water additives. Mind control. The government refusing to comment
on the existence of aliens. The yellow test kit has exposed it all!

How else did Arnold get elected?
