The bio polymer sphere not only maximizes the biological filter performance of the unique sintered glass tube but at the same time also increases the holding time of the filter in two ways. Besides pollutant breakdown, the special construction of the sphere optimizes the water flow and thus improves substance transport into the inner siporax ring. sera siporax Nitrat-minus Professional therefore is an almost maintenance free and, above all, long lived filter medium. The number of water changes can also be reduced. Water parameters can be improved by siporax Nitrat-minus Professional especially in bigger and/or densely stocked community or cichlid tanks.
sera siporax Nitrat-minus Professional can be combined with siporax products already present, such as siporax Professional, siporax mini Professional and siporax pond Professional. By providing carbon, it will improve pollutant breakdown there as well.
