WHY do you have ammonia in the tank to begin with?
You are thinking of an ammonia neutralizing product like Prime... Prime converts ammonia into ammonium (much less toxic form)... when you test with a kit like API, the test actually ups the ph of the water to like 14 for the test... this releases the ammonia that was in the form of ammonium and gives you a false positive.
But you shouldn't have ammonia in your tank if it's properly cycled... if it's not cycled, an ammonia removing product like ammo chips will only screw with your cycle.
