FMR75 Fluidised Media Reactor

The FMR75 Fluidised Reactor has been developed by D-D to give the ultimate economic solution for fluidising a whole range of materials that are used on your marine or freshwater aquarium.

Many smaller reactors on the market look good, are packaged well and are competitively priced however when you get down to using them they just do not tick all of the boxes. D-D have spent a lot of time ironing out the bugs to make this a flexible product, ideal for all hobbyists.

Suitable for
Rowaphos or Phosphate Removers
Nutrifix Bio Pellets (Up to 700ml)
Carbon
Biological Sand as a fluidised sand filter
Dimensions
These reactors are small enough to use on the smallest of nano tanks but with sufficient capacity to use on larger systems.

128mm x 94mm x 440mm (including fittings and lid)
Reaction tube outer diameter - 80mm
Tube height between upper/lower perforated plates - 340mm
Can hang on glass up to 25mm
Designed to be the correct height to hang on a 15" sump (will stand inside smaller sumps or hang onto taller sumps).

FMR75 Fluidised Media Reactor with pump: FMR 1000 pump size 100mm H x 60mm W x 90mm L

Plug & Play
How often do you buy some equipment and then find you do not have all of the parts to install it?

The FMR 75 reactor is supplied with all of the items that you need to allow you to get going.

FMR reactor
3 x lengths of clear plastic tubing
Non return valve
Flow adjustment tap
2 Grades of media sponges (1 of each)
8 x cable ties for securing the pipework

Flexibility
It is important to be able to mount the reactor in a range of positions depending on the system. The FMR75 can stand in the sump, beside the sump, hang on the sump or hang and clamp directly on the tank via the bracket incorporated into the lid design. The inlet and outlet pipes can be fitted in a number of positions to allow pipework to run in different directions.

Loss of Media
Many reactors are not fitted with any type of barrier to stop the media from passing out of the top of the reactor and into the aquarium, relying simply on reducing the flow rate so that the fluidisation is within the bottom 2/3 of the reactor. Anyone who has used a reactor will know that on start up that you get a sudden flood of water which washes a portion of the media out before the fluidisation settles down.

The FMR75 is fitted with an upper perforated plate and also with a fine sponge to restrict all but the finest of particles from exiting the reactor in this situation.

Note: When used with Bio Pellets that the upper sponge should not be used however the perforated plate will prevent the media from being flushed out of the reactor.

Non Return
In a power off situation, where the reactor sits above the water level, the water and media will back syphon through the pump. The FMR75 is supplied with a non return valve which can be used if required, depending on installation, and prevents this problem from occurring - simple but effective.

Important Note
The hose connectors on the top of the reactor are designed to be a tight push fit, however if the unit is to be used outside of the sump then we recommend that you glue these in position with aquarium silicone for extra security once the final position is determined and connect all hoses with the cable ties supplied. This will provide extra assurance if the connectors were not connected properly in the first place of if the unit is knocked accidentally.
