element™ M Media Reactor

Versatile, compact media reactor for up to 100 US gallons/380 liters

The element™ M Reactor is a filter media reactor that allows for the use of virtually any type of filter media in either fluidized or non-fluidized flow - including fine particle media such as resins. The element™ M Reactor allows for excellent efficient reaction with consistent even flow from the bottom of the reactor to the top. Using the adjustable internal plate, filter media can even be separated to allow for various uses within the same reactor. The element™ M Reactor features a by-pass valve which allows for fine flow regulation for even the most delicate media such as beaded resins.


Easily Removable Inner Chamber

The inner chamber can be removed without full breakdown making it easy to clean, change or top off media

Movable Separation Plate for Various Volumes of Media

The separation plate can be moved up and down which allows you to run any amount of media in a compacted fashion, preventing sheering of media

High Capacity Chamber

The reactor chamber can hold up to 1.2 Liters of your choice of filtration media

Sensitive and Versatile Flow Regulation

Offers highly controlled flow rate for running any type of media at any speed (even resins such as Seachem Purigen® or purfiltrum™) .

Polishing Mechanical Filter Finish

The included addition of a fine filter sock finish acts as a fine mechanical filter so no media particles escape into system. It also prevents micro bubbles from being released into the aquarium to irritate corals

Powerful External Pump

Allows for higher column flow volume with more contact time and surface area. Allows for easy maintenance of the pump at anytime.

Versatile Sump Placement

The element™ M and element™ Z have added versatility in positioning the return spillway. So depending on the size of your sump and placement of other equipment, you can always find a good fit.

Fluidized or Non-fluidized Media

Allows for running of any type of media as a fluidized bed (biogen™) or as non-fluid bed (Seachem MatrixCarbon™)

Easy Maintenance

The element™ M can be quickly and easily dismantled for maintenance and thorough cleaning.

Anti-Vibration O-rings and Rubber Feet

Additional sound-dampening features assist in silent skimmer operation

Patent Pending Compact Base Design

Designed with a compact footprint in mind to fit in virtually any sump

Operation is Independent of Water Level in Sump

Variations in sump water level don't impact the function of the skimmer

3 year warranty

The element™ M is guaranteed against defects of materials and workmanship for a period of 3 years from the date of purchase, except for the pump’s impeller. This can be extended to 5 years by registering your skimmer. The warranty covers the replacement of the defective parts.

Setup Versatility

Single Packed Media

In this method, a single media or media blend is used within the entire reactor.

Dual Packed Media

In this method, two media are used and separated by the separation plate

Fluidized Media

In this method, the media is allowed to tumble freely (fluidized) in the reactor chamber

A: Are the teeth facing the right way? If we could include a picture from the manual to show the correct direction of the teeth that would be helpful!

A: There is a ball in the valve where the pump connects. The ball prevents any back flow in the case of a power outage or pump failure. The rattling is just the ball hitting the sides of the valve. If you would like to remove the ball, you may do so at your own risk.
