A biofilter is a biological filter that provides a pond with water that is rich in carbon dioxide. Carbon dioxide is very important for water plants. They, in turn, keep pond water clear and clean.
What does a biological pond filter do?
Biological Filtration A biological filter works like a mini sewage system for the pond. In simple terms the media within the filter creates a huge surface area, which becomes home to many millions of helpful bacteria. It is vital to keep these oxygenated by passing pond water through the filter 24 hours a day.
What is biological filtration of water?
Biological filtration is a general term referring to the process of using beneficial bacteria to clean the water on a molecular level. In a natural stream or river, bacteria colonize on the stones and pebbles at the bottom of the stream, which naturally breaks down toxins as the water flows around.
What is the biological stage of a pond filter?
Like mechanical filters, the biological filtration stage also contains media known as biological media. These typically consist of small pieces of plastic, bio-balls or many other small objects which act as a huge surface area for bacteria to colonise and grow.What do you understand by biofilter?
Definition of biofilter : a filter bed in which sewage is subjected to the action of microorganisms that assist in decomposing it.
Do all ponds need a pump?
A pond pump circulates and aerates the water which helps to maintain a healthy pond environment. There are two basic types, a submersible and an external pump. But, not all ponds need a pond pump as we will go on to explain. The closed ecosystem of a garden pond needs to be carefully managed.

What can be used as biofilter?
Most biofilters use media such as sand, crushed rock, river gravel, or some form of plastic or ceramic material shaped as small beads and rings.
What is biofilter state its principle of action?
Biological Filtration. The principle of the biofiltration process is similar to that of the activated sludge process. In this process, the organic matter (food) is brought into contact with high numbers of microbes (film adhering to media) in the presence of oxygen (Figure 8).
Does a waterfall oxygenate a pond?
A waterfall will aerate a pond, but it has its limitations. If your pond is small and shallow, a waterfall might create enough circulation to cover the entire volume of water. However, if you have a large, deep pond, a waterfall will likely be inadequate on its own, and you may need extra help.

What are the 3 types of filtration?
The three main types of filtration are mechanical, biological, and chemical filtration.
How often should I clean my biological pond filter?

In general the BioFall filter pads can last up to two years, we recommend not going more than two years on a set of pads.
What bacteria eats fish poop?
Nitrifying bacteria aka the good or beneficial bacteria, are present after successfully cycling a new tank. Nitrifying bacteria provide natural biological aquarium filtration and are responsible for breaking down organic waste within the fish tank.
Is biological filtration important?
Biological filters enable bacterial colonies to propagate and break down wastes. Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates.
