The Fauna Marin Multi-Filter is a versatile media chamber that can be used as a bio-pellet reactor or media reactor.
As media reactor, the Multi-Filter can hold various types of filtration media:
- Fauna Marin Carb L activated carbon
- Fauna Marin NPO Redu pellets
- Fauna Marin Phos 0,04
- Fauna Marin Power Phos
- Fauna Marin Ultra Phos
- You can also comfortably mix Carb L and PO4 media together in one chamber without any issues.
The Multi-Filter’s space saving design allows for users to find a spot for it in even the smallest of spaces!

Assembly and Installation
Step 1 Assemble the Multi-Filter by connecting the included pump to the body of the filter. Make sure the pump is fully open, see operating instructions enclosed with the pump.
Step 2 Find a suitable area in your sump and place the Multi-Filter in that area. If possible, position the filter in front of a skimmer. This will allow the reactor media to more efficiently reduce nutrients. The reactor should not sit in a water level above 9.8″ – 11.8″. Make sure the reactor is standing straight at all times. Otherwise, performance will be compromised.
Step 3 Remove the upper middle screw and screen, then add your filter media of choice. Re-position the screen and slightly tighten screw.
Step 4 Adjust the pump outflow rate by turning the dial on the pump itself. Make sure the filter media is tumbling gently and not getting tossed around the reactor.
Ensure that the filter media is always tumbling and getting sufficient water flow.
In order for the reactor to maintain performance, we recommend you perform regular maintenance on the reactor.
- Clean the upper screen with a soft brush
- Clean the drain openings with a soft straw brush or pad
- Clean the outer side-walls of the reactor with a pad
2 week maintenance
- Clean pump body
3 – 4 week maintenance
- Remove and clean lower screen by disassembling the reactor body.
- Open center screw of the PVC pipe, remove upper screen.
- Turn the lower screen on the center PVC pipe (threaded at the base)
It is very important to make sure that the water is overflowing evenly throughout the reactor’s outer walls. This allows for the drain water to be re-enriched with Oxygen which was previously consumed during the nutrient decomposition phase.
Use the flow-adjustment knob to fine-tune the reactor flow rate and ensure that the reactor runs quietly.
