If you add Prime - it binds the ammonia - it doesnt remove it. So - depending on the test kit you're using - you can still see measurable ammonia after using Prime. Sorry if this was mentioned already.
By the way, this means that your ammonia is fine, i.e., not a problem. There are tests for 'free ammonia' which is the toxic 'version'. Which test did you use?
