ALL urine breaks down to ammonia. In ancient Rome, urine was collected from the public restrooms, let turn to ammonia, for cleaning wool clothing. In America pre-colonization, the Native Americans used urine let turn to ammonia to cure hides into leather.
In still other countries it was used for setting colors when they dyed fabrics.
When the ammonia gets high in a fish tank the fish die. Where does the ammonia come from? The fish urine.
