2. Working principle of the Nitratereductor
In the Aqua Medic
Nitratereductor NR Blue
the water is treated anaerobically. In the absence of
oxygen, many bacteria are able to use nitrate as a substitute for oxygen for their metabolism.
The oxygen is used for the metabolism, the nitrogen is excreted into the water. Nitrogen gas is a
natural compound of the water and totally harmless. It is, however, necessary to increase the
metabolism of the bacteria so that they can reduce enough nitrate. For this reason, the nitrate
removing bacteria have to be fed. This food contains organic substances that can be used
completely by the bacteria. The only waste product is CO
2
.
In
the Nitratereductor NR Blue
either
Denimar
or
Mini-Deniballs
can be used for feeding.
The flow rate through the
Nitratereductor
is very slow. This is the main difference to other
aquarium filters where the water is often treated once per hour or even more often. The water in
the
Nitratereductor
should have a retention time of 4 hours. If the filter is adjusted correctly, the
water leaves the filter nearly free of nitrite and nitrate.
