ammonia tests show low levels?

Is it possible to have ammonia present (enough to stress fish and/or cause algae) when the test kit shows nothing present (yellow). I use the AP liquid test.

No if that test shows the water to be yellow which means no ammonia then you dont have any. That is a pretty good test kit..
