How does Phosphate Reactor works

[foo_pat]

Had bought a RAD brand fluidized bed reactor, added phosphate remover media but it don't seem to have the media moving up and down as bio pellet

Is it normal? N I also realize that after 4hrs after installation, the water remains cloudy

Any advice on this?

Are you using Ultraphos?

You gotta flush out the cloudy water until becomes clear or less cloudy
