Bacteria play a key role in the nitrogen cycle. Nitrogen enters the living world by way of bacteria and other single-celled prokaryotes, which convert atmospheric nitrogen— N 2 —into biologically usable forms in a process called nitrogen fixation. Some species of nitrogen-fixing bacteria are free-living in soil or water, while others are ...

The Nitrogen Cycle

Before discussing the nitrogen cycle in detail, let's look at the three main components: ammonia, nitrite, and nitrate. Ammonia. Ammonia, or NH 3, is the natural product of fish waste. When fish are added to a new aquarium (an aquarium without a built up biological filter), the ammonia will build up.

The Nitrogen Cycle: Understanding Biological Filtration

The nitrogen cycle, which occurs in both freshwater and saltwater systems, is a series of naturally occurring biological processes whereby the harmful byproducts of decaying organic matter (ammonia) are ultimately converted into less harmful species (nitrates and/or nitrogen gas.) It starts when ammonia (NH3 or NH4) enters the fish tank ...

Nitrogen Cycle Explained

Nitrogen Cycle Definition. "Nitrogen Cycle is a biogeochemical process which transforms the inert nitrogen present in the atmosphere to a more usable form for living organisms.". Furthermore, nitrogen is a key nutrient element for plants. However, the abundant nitrogen in the atmosphere cannot be used directly by plants or animals.

Beginners Guide to the Aquarium Nitrogen Cycle

The complete nitrogen cycle. 1. You feed your fish food, and any uneaten food becomes waste.

. 2. Your fish eat the food and poop – more waste. 3. The waste in your tank builds up. 4. As the waste begins to break down and decay, it …

Nitrogen Cycle in Pond Filtration

Understanding the nitrogen cycle is essential for effective pond management. The Nitrogen Cycle in Pond Filtration. The nitrogen cycle is a series of biological and chemical reactions that involve nitrogen compounds in the water. In a pond or aquarium, this cycle typically includes the following key steps: 1.

How to Boost Up Your Tank's Nitrogen Cycle (The Ultimate Guide …

Nitrifying bacteria – the bacteria that feed on ammonia and nitrite – grow best in the dark. As tempting as it is to switch on your tank's lights so you can admire your aquascape, wait until your nitrogen cycle is complete first! If you have any plants, keep your light exposure down to a maximum of 10 hours a day.

The Nitrogen Cycle

What is the Nitrogen Cycle? Fish waste, uneaten food, and decaying plant matter all produce ammonia. Ammonia is poison to your fish and must be removed. When ammonia is present in an aquarium, a bacterium called Nitrosomonas will start to form. Nitrosomonas oxidizes ammonia and puts off a byproduct called nitrites.

Nitrogen Cycle in Aquariums

Nitrogen Cycle. The natural nitrogen cycle is a full cycle where nitrogen goes from air to plant to animal to bacteria and back to air; such a system needs no human intervention. In an aquarium though, the nitrogen process is less a cycle and more a biochemical cascade that involves the continual chemical degradation of nitrogenous …

Aquarium Nitrogen Cycle

Aquarium Nitrogen Cycle Stages. Stage 1. Ammonia is introduced into the aquarium via tropical fish waste and uneaten food. The tropical fish waste and excess food will break down into either ionized ammonium (NH4) or un-ionized ammonia (NH3). Ammonium is not harmful to tropical fish but ammonia is.

There are three stages of the nitrogen cycle and every new aquarium must go through these three stages before biological filtration is fully functioning. The largest contributing factor to fish loss/death in aquariums is a failure to understand this process and provide the right conditions for it to occur.
