You can now have a look at a NPF150 running on youtube...

The tumble rate and input/output of water within the reactor, operate independently of each other, giving you the opportunity to either run at maximum flow when the phosphate and nitrates are high .. and when the parameters are met ... decreasing flow to the bio pellets to cater for the lower levels... keeping them under control.

Comes with a 'easy fill' union.. no need to open the reactor to add media.

Also due to its pressurised design allows you to sit the reactor below the water level ... allowing the Bio Pellet reactor to sit in the cabinet while pushing the effluent back to the raised aquarium above

Can be used in sump or free standing.

Everything you need to get going .. well .. just add media.

The maxijet 1000 is a Dual voltage pump and can be used with both 220v - 240v and 110v - 120v electrics.
Plug adapters maybe required to do so though.. as pumps come with uk plugs fitted.

NPF150 Kit Consists Of :

NPF150 Reactor, Maxijet 1000, Control Valves and 2m of 12mm piping.

Maximum Output Flow (750mls of Media): 200lph

Maximum Media Capacity: 750mls (dependent on media used)

Dimensions (mm):

Height: 450

Footprint: 130

Column Dia: 90

  • Instructions

    1. Fill NPF reactor with Bio pellets/ pearls media to desired level… no need to open the reactor… pour the media through the PVC union. Now fill the reactor with water, once full to the union lip. Refit the union and tighten.

    The reactor has been pressure tested so no need to tighten any nuts.

    2. Fit tubing to inlet… the hose on the off-set 90o elbow.

    3. Then run the piping to the aquarium/ sump where water is going to be 'drawn to the reactor and place in water. And cut to length.

    4. Then fit tubing to the outlet of the reactor… this one is the hose situated just below the PVC Control Valve.

    5. Place Control Valve on the outlet hose and run hose to the inlet or close to the inlet of a protein skimmer.

    6. Place control valves to de-gas chambers.

    7. Close outlet valve and suck remaining air from the reactor by means of the ‘de-gas’ chambers. The degas chamber is situated on the upper most fittings.

    8. Close degas control valves when all of the remaining air in the reactor is gone.

    9. Add power to pump.

    10. Adjust PVC ball valve to allow required flow and allow effluent to run to the inlet of a skimmer. The skimmer is needed to remove heavy matter produced by the bio pellets and allow re-oxygenation of the water.

    12. Open exit valve slowly till you get required flow is achieved


    The PVC Valve may require the valve to be slightly closed. This is to add back pressure, so that the water will drawn and push water from the reactor.


    For high nitrates or phosphates run near fully open and test the effluent over the first week to acquire whether flow rate is removing the nitrate and phosphate. Once the phosphate and nitrate are within acceptable levels reduce flow and test once more within the week and adjust flow once more to match levels.



    1. A Pre filter is recommended. This will collect and stop detritus from entering the reactor, spoiling the efficiency of the bio pellet reactor.

    2. Vertical Position of Reactor is required.

    3. The reactor can be sited in sump or free standing
