Is my Phos reactor fluidizing properly?

[yraveh]

Good Morning.

I have installed yesterday a 2 little Fish Phosban Reactor with Rowaphos media (~200ml). I am running it with MiniJet 404 at maximum 106 GPH . the flow valve is wide open. However I see only the top 1" of the media fluidizing. The lower 2/3 of the media seems packed.
Is this is how it supposed to be?

Can the media harden to a rock in its lower part? If so, will I be able to remove it?

Yes you will be able to remove it as it does not harden as much, on the fluidization actually it is not so the flow should be barely enough to rise the media (Rather than fluidize it) and you shall be able to see just some movement on the surface of the media but I think the top 1 fluidizing might be too much flow.
By the way, Phosban and Rowa tend to chanel trough the media. There is a product PHOsR that is pelletized and will give you better unifor flow across the media.

Great! i am relieved to know that the pump is strong enough. I thought the whole media is supposed to be swirling all over the water column inside the reactor. I will adjust it down.

Phosar was my first priority. marinedepot does not sell it and I wanted to take advantage of the free shipping. I am looking for the PHosar HC for my next purchase.

Note that PHOsR HC although it has higher capacity for adsorption is not pelletized.
