A newly setup aquarium or pond does not contain very many bacteria. Once fish are introduced, ammonia (NH3) will begin to be added to the tank from uneaten food and fish wastes. In acidic waters (pH < 7), the ammonia will combine with hydrogen cations (H+) to create ammonium (NH4+) which is not very toxic.
