Yes the FMR75 reactor is ideal for running Rowaphos in either a freshwater or saltwater aquarium.

The FMR75 will hold around 700ml of media.

When running Rowaphos in a fluidised reactor it only needs to be lightly fluidising, just enough to see the surface of the media moving.

It is also best to run with the unit with the fine sponge at the top and the coarse one at the bottom.
