Micro-organism as the biological cleaning brigade

aquavital zeranix is a highly porous filtering medium for the colonisation of micro-organisms. The micro-organisms in these filters represent the biological cleaning brigade. They digest rotting matter and fish faeces, and transform the toxic products of metabolism, for instance urea, ammonium, ammonia and nitrate, into plant nutrients, thus making them indispensable for healthy plant growth.


Natural living conditions in the aquarium.

Healthy fish and plant growth in an aquarium presupposes the effective breakdown of harmful substances in the aquarium water. The filtering system removes faeces, dead plant matter and the protein residues of fish feed, thereby ensuring healthy living conditions in the aquarium and keeping the water crystal clear.


The surface structure is vital!

aquavital zeranix is a natural silicate mineral that is characterised by 85% porosity and an extremely large surface, thus providing the optimal structure for the colonisation of micro-organisms. In addition to the external surface and the internal micro-passages, the material also has microscopic cavities that areopen on one side. This optimal structure enhances the formation of aerobic zones and the necessary anaerobic zones for breaking down the nitrates contained in the water.

aquavital zeranix is chemically neutral and does not influence the hardness or the pH-values of the aquarium water. It can be used for both freshwater and sea water.
