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.

Weekly maintenance

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)
Our recommendation

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.
