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.
The Reactor is available in two versions; one with and the other without a 1,000l/hr matched pump.
- Rowaphos or Phosphate Removers
- Nutrifix Bio Pellets (Up to 700ml)
- Biological Sand as a fluidised sand filter
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).
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
Affordable Quality Build
The FMR75 Reactor is affordable enough to be used on small tanks or to allow multiple units on larger tanlks, however there is no compromise over design and build quality as it is no good having the best reactor in the world if it breaks after 5 minutes of use.
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.
The main requirement of the reactor is to fluidise media efficiently which the FMR reactor does very well. The base of the body is dished to disperse an even flow of water from the central downpipe through 360 degrees, preventing dead spots.
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.
Ease of Ability to Refill
Many reactors make it difficult or impossible to refill the media without emptying out the reactor first as the central tube comes off with the lid. This and the lack of a lower diffusion plate means that the media fills the tube when you put the lid back on, making it hard to restart.
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 has a non return valve supplied separately which can be used or not, depending on installation, and prevents this problem from occuring – simple but effective.
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 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.
