For simplicity of use and to maximise the life and effectiveness of the media we recommend that RowaPhos should be fluidised in a fluidised reactor. This method makes the whole surface area available for adsorption from the water stream.

We recommend the Deltec FR Series Reactors for this purpose, which were specifically designed for handling this media.

When fluidising RowaPhos we suggest that the media is first flushed through in the reactor with fresh water to remove any fines, which would otherwise temporarily discolour the tank. The fines are not harmful but may be seen by some as unsightly especially if they settle on the base of the aquarium or on rocks.

Note that this advice is contrary to that given for normal use in a sock or canister filter where we recommend that RowaPhos is used unwashed.

To flush the media, first place it in the fluidised reactor and then connect the reactor to a freshwater supply. Slowly feed water through the unit being careful not to over fluidise the RowaPhos, discarding the brown water that first exits the reactor.

When this water starts to clear, switch off the water supply and carefully tip the reactor to remove any excess fresh water above the media.

Connect the unit back up to a saltwater feed and carefully turn on the flow until the surface of the RowaPhos just starts to move. Any remaining discolouration of the water will quickly disappear.
