• This filter material is home and food for bacterias.
  They only need oxygen to breath. With their ability to break nitrate into its components nitrogen(N) and oxygen(O) this need is covered.
  To make sure that nitrate is used, oxygen should be of low value in the water (slow flow recommended).
  The reduktion will take place as following: NO3 > NO2 > N2O / N2 (nitrogen will be removed to the atmosphere).
  For fast activating we recommend our living filter bacterias / our product "biorein".

Info: You can test the quality of your filter material very easy. Take a glas or bottle with opener, fill it half with the filter material and then fill it up with nitrate polluted aquarium water. Make sure that no air remains before you close it.
The few bacterias in the water find an environment of low oxygene. Good filter material can now be colonised by the organisms and also used as a sorce of food. In the first week there will be no effect because in order to eliminate bigger amounts of nitrate the quantity of bacterias need to expand.
