The Nitratereductor NR 1000 is an anaerobic biological reactor for removing nitrates from marine and freshwater aquaria up to 250 gal. It has a 4.5 gal. volume and an internal circulation pump. It works with a flow rate of 0.25 – 1 gph. The Nitratereductor NR 1000 is a closed unit that can be integrated into filter systems, but may also be installed stand alone under the aquarium. To monitor this process, it is possible to use a redox potential controller (ORP controller) in conjunction with an electrode inserted in the built-in PG13.5 port or the Dosing pump SP 3000 (supplied) can be connected for a fully controlled system.
Dimensions: excluding electrode (l x w x h): app. 7 x 7 x 22 in.
