Here is an article about how Amquel works (same method as Prime):

The ammonia is converted to an amine and bonds to a sulfur molecule, ie aminomethanesulfonate. It does NOT just get converted back to ammonia but goes through the normal biological nitrification.
Amquel+ compared to Amquel:
AmQuel+ - how it works, compared to regular AmQuel
the complexes in AmQuel+ detoxify any chloramines, chlorines, and nitrogen compounds present in the water. AmQuel+ splits apart the chloramines (composed of chlorine and ammonia), detoxifies the chlorines in seconds and the ammonia within five minutes. AmQuel+ breaks the toxic nitrogen compounds in the water apart, gassing out their oxygen and hydrogen components out of the water into the air, and preventing the nitrogen compounds from recombining in toxic form. These compounds include all the ammonia/ammonium, nitrites, nitrates, pheromones, and all other toxic organic compounds for which there are no common names -- yet are important to detoxify to be harmless to fishes and other aquatic life. The nitrogen components are mostly detoxified within five minutes and the slight remainder is detoxified over the next 24 hours. The compounds now broken apart are in the detritus and transparently soluble in the water. They are consumed over time by the sewage-consuming bacteria and algae.
