What is a biological filter?

A biological filter or "bio filter" is simply a home for the beneficial bacteria that perform the nitrogen cycle. The filter provides surface area that the bacteria can live on and a recalculating water pump ensures that water is constantly flushing over the bacteria so they can obtain their necessary nutriment and oxygen.

Why is it important?

By eliminating the organic waste compounds in the water, biological filtration detoxifies the water and makes it safe for fish. Additionally, by removing the organic waste compounds, algae is controlled because those compounds are the nutriment that algae require in order to grow.
