ammonia is what is givin off threw a fishes gills when it as to say exhales.
You mean carbon dioxide. Last time I checked that's what animals produce as waste when they breathe. Ammonia is from other "waste" products.
Fish also give off ammonia via the gills. As blood is carried through the gill filaments, ammonia (and carbon dioxide) is exchanged to the water and oxygen is absorbed.

I agree with the others... the best way to keep ammonia out of your tank is to control ammonia spikes caused by overfeeding, overstocking, misuse of meds/chemicals, etc. Let the nitrifiers do their job.
