Filtration system is the lifeline of any aquarium, terrarium and pond. Conventional filtration systems incorporates the use of physical and particle filters. However, these are not as effective as desired, because the organic composition of the medium remains the same.

With biological filtration, the treatment is focused on the medium - the water. Biological filtration promotes the propagation and growth of bacteria, which in turn optimises the nitrate level and reduces the nitrite level naturally.

Oriental Aquarium manufactures and supplies the most crucial component of such filtration systems - Biological Filtration Balls, in bulk quantities.
