The Nitratereductor NR 5000 uses the same biological principle as our smaller model and is used for aquaria up to 800 gal. It has a volume of approx. 7.5gal., and is supplied with an internal circulation pump, plus the connection for a pressurised 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. It is a closed system, and should be supplied with water via a bypass or a dosing pump at a rate of 3-8 gph.
Dimensions: excluding electrode (l x w x h): approx. 20 x 12 x 38.5 in.
