The Superfish BioBox airlift biological filter provides effective filtration of the aquarium water.
The box contains a layer of filter wool, a sponge for biological filtration and maifan stones, these absorb toxic substances (i.e heavy metals) from the water and ensure that the pH remains neutral.
The Superfish BioBox filter must be connected to an air pump (not supplied) to create a movement of water that allows the box perfect biological filtration.
