The Aqua Medic Nitratreductor NR Blue (410.760) is an anaerobic biological reactor for removing nitrates from salt- and freshwater aquaria. It has a 5 l (c. 1.2 gal) volume and an internal circulation pump. The Nitratereductor works with a flow rate of 1 to 4 l/hr (c. 0.25 to 1 gph). In the absence of oxygen this situation promotes bacteria that metabolize nitrate. Denimar-powder or Deniballs are used as an organic energy source. The Nitratereductor NR Blue is a closed unit that can be integrated into filter systems, but may also be installed to stand alone under the aquarium. Deniballs and BactoBalls included
