Product Information

The Aqua Medic Nitratreductor 400, available from Swell UK, is a completely sealed biological filter. It is operated at a very low flow rate so that an oxygen free environment is created wherein naturally occurring bacteria reduce nitrate to harmless nitrogen gas.

The filter can be installed in almost any position, inside or outside the aquarium or the cabinet.

For the water flow, we recommend the Dosing pump SP 1500.

After maturing the filter can keep the nitrate concentration in a normally loaded aquarium up to 400 litres at a very low level.

The unit uses Deniballs and they will require replacement in 9 to 12 months dependant on load.

For optimum control we recommend the filter be used in conjunction with an Aqua Medic mV controller or an Aqua Medic mV computer. The filter is already equipped to accept our pressurised electrode.

Dimensions (without electrode):

  • 14.4 x 10 x 37 cm. (LxWxH).
  • c. 5.8"x 4" x 14.5" (LxWxH).
