Biological filtration in the aquarium - is it necessary?

Biological filter in the aquarium is responsible for removing invisible nitrogen compounds that accumulate in the water. The presence of harmful toxins is largely due to fish. They excrete metabolites that contain nitrogen compounds. Some of these are absorbed by aquarium plants, while the remnants are broken down into ammonia. This, in turn, reacts with water, creating harmful ammonium ions. Their content can be limited through continuous water exchange or by installing biological filters that allow the development of anaerobic bacteria. Accessories provide the ability to control, effectively removing contaminants. The biological filter media provides ideal conditions for the growth of a specific strain of bacteria beneficial to plants and animals. The larger the active surface area, the less frequent the need for water exchange. Moreover, the biological filter is one of the factors that ensure appropriate conditions for breeding tropical fish and aquarium plants.

How to choose a biological filter for the aquarium?

Biological filters for aquariums come in various designs. They should be chosen based on the size of the tank. Remember that the biological filter should pass all the water at least once, and the optimal situation is when it can filter it 3 times within 60 minutes. Furthermore, the larger the surface area of the biological filter media, the more bacteria can grow on it. They are an invaluable aid in the case of large tanks. They ensure crystal clear water free of any contaminants.
