The Nubios Bio Filter ceramic tubes can be used to direct the flow of water in the filtration and distribute the flow evenly and they are indispensable for efficient mechanical filtration. Due to its high porosity and large surface, the ceramic rings ideally support the growth of bacteria. Nubios Bio Filter ceramic tubes are available in 3 versions (9, 13 and 16 mm diameter) and are supplied in a handy zippered fabric net.
