The difference with other filtration media is that the Aquaroche modules can shelter both bacteria and micro fauna, including microscopic worms which find galleries, wide and deep enough to penetrate to the heart of the rocks.Aquaroche Live rock Function Filter elements have a great deal of open cells of 20/100 µ, linked together by galleries and fissures of 100 µ to 1 mm.The shape is a cube of 5 cm, big enough to enable the development of areas poor in oxygen.To better imagine the size: a bacterium measures around 1 µ, each element is a micro world cube of 50 000 µ side. To bring it to a human size, if the bacteria measured 1 meter, the cube would measure 50 kilometres.
