What is Aquarium Ammonia detoxifier and how does it work?

Many pet owners know that the smell of ammonia is one of the worst culprits in an aquarium. Ammonia is a gas emitted from fish waste and uneaten food. This gas is actually a byproduct of fish metabolism and is a necessary one for the balance of the ecosystem in aquariums. Ammonia is a toxin that can lead to suffocation and death in high concentrations, but is converted into less harmful substances such as nitrates and nitrogen by bacteria found in filter. The Ammonia Detoxifier also has two other functions, removing nitrites and nitrates. The Ammonia Detoxifier uses an enzyme reaction to oxidize ammonium ions into harmless nitrogen gas releasing ammonia gas. These act as natural ammonia filters. They also provide a safe spot for your fish to hide.
