Nitrate Filter ADN & POC

Nitrate Filter ADN & POC

In modern reef tanks the nitrate concentration should be between 5 and 20 ppm to ensure best growth of corals and to reduce the danger of a green algae mass production.

If you feed much and you have many fish in your aquarium nitrate will accumulate with the time. If you cannot lower the concentration with water change, trickling filter or living stones you need a nitrate eliminating filter system.

As a basic principle you can differ between autotrophic (bacteria cut their carbon source from inorganic matter) and heterotrophic systems (bacteria cut their C-source from organic matter).

You do not have to feed autotrophic systems - an organic pollution cannot happen. But autotrophic systems have a little bit longer run-in phase and the operation pH is over 8.0.

Heterotrophic system have to be fed with organic substances, e.g. alcohol, acetic acid, sugar, PHB = polybetahydroxi-butyric acid, starch, etc.. If quickly soluble organic C-sources are used it is possible that an organic pollution occurs. This pollution may cause a bacterial bloom coming along with oxygen shortage. The run-in time is short.

Pellet filters (POC filters) operate under oxygen-containing conditions and are not denitrification filters. They remove nitrate by so-called bacterial assimilation. 

If you are looking for larger systems please choose the industrial version of ADN.

Spare parts for your filter can be found on the respective model under the tab "Spare parts" - if you do not find something, just ask us.
