During the bacterial breakdown of organic, nitrogen-containing substances such as food remains or fish feces, ammonia or ammonium is released. Which of the two substances is formed depends on the pH value of the water. Ammonium in acidic to neutral water is less toxic than the highly toxic ammonia in alkaline water. Both substances are further broken down by beneficial bacteria, as part of the nitrogen cycle, into nitrite and then into nitrate. In a well-functioning aquarium, the ammonium/ammonia value should be below 0.25 mg/l.
