The Nitratereductor NR 5000 is an anaerobic biological reactor for removing nitrates from salt- and freshwater aquaria. It has a volume of 30 l (app 7.5 gal) and is supplied with an internal circulation pump, plus the connection for a pressurized redox probe with a PG 13.5 thread. Feeding the bacteria can be performed manually with denimar or automatically using Deniballs in conjunction with an mV (ORP) controller. The Nitratereductor NR 5000 is a closed system and should be supplied with feed water via a bypass or a dosing pump at a rate of 12 – 30 l/hr (app. 3 – 8 gph).
Dimensions excluding electrode (l x w x h): app. 50 x 30 x 96 cm (app. 20” x 12” x 38.5”)
Recommended accessories: denimar-powder and Deniballs to feed the anaerobic bacteria, pressure resistant mV (Redox or ORP) probe with PG 13.5 threaded connection.
