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


Element reactors are designed with the reef aquarist in mind. These reactors offer a host of features including: versatile and compact design, high capacity 1.2 liter chambers, powerful pumps, easy setup and maintenance, an easily removable inner chamber, and operation that is completely independent of sump water level.


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.

Media Reactor
Highly versatile media reactor with controlled flow rate, that allows for running fluidized (biogen) or non-fluidized bed media (non-fluidized MatrixCarbon) at any speed. With a fine filter sock for final mechanical filtration, no media particles can escape into the system.
