High Performance Biological FilterThree different types of filtration in one filterare the basis for the best filter characteristics.1.Organic chemical filtration. Thepatented air liftensures anoptimal turbulenceand anoptimal input of oxygeninto the water. On the other handCO2 is degassedin huge quantity.2.Glass, ceramics and natural stone form the basis for thehighly efficient biological filtration.Due to a high temperature process, ahighly porous surfaceis generated. It is optimally suitedfor the colonization of filter bacteria. Compared to other ceramic biofilters, it is3 to 5 timesmore efficient. This leads to amore stable water qualityand to abetter ecological balance.3.Amulti-layered spongeis used as pre-filter. Itquickly absorbs the impuritiesin the water anditcleans effectivelythe suspended sediment.Thepatenteddesign and the structure allow a high density of nitrifying bacteria. This results inefficient filter performance, alongevity of the filterandeasy handlingduring cleaning.For use you only plug the air hose onthe connecting piece.Item no. 30086For tanksup to 350 Liters(100 Gallons).When using a proper air pump, theoutput of water can reach more than1.000 Liter/h.Item no. 30085For tanksup to 150 Liters(100 Gallons).When using a proper air pump, theoutput of water can reach more than400 Liter/h.
