API® AMMO LOCK ammonia detoxifier is scientifically proven to protect fish against harmful ammonia by converting poisonous ammonia into a non-toxic form.

Note that if your aquarium tests positive for ammonia, it is necessary to perform a partial water change first, and then neutralize the ammonia.
