Difficult to see properly but I would agree at around 4 - same test kit as mine![]()
I would leave for an hour after doing the water change before testing - as you may have for a more accurate read, so if you did wait that should be ok.
How is the tank water looking - clear, cloudy or murky? mine goes cloudy for a few hours after adding the ammonia.

Paul,
The problem is I have not added any Ammonia that test was taken 1-2hours after a 40% water change!
