Proper way to use Purigen

[Metasyntactic]

I'm setting up a canister reactor of Purigen and was unsure of whether I should allow it to be fluidized. I know that GFO should be allowed to tumble to improve it's exposure with water and that activated carbon needs to have less motion to keep it from grinding itself into fines but I can't find a solid answer for Purigen. It seems like it should be allowed to fluidize but I want to make sure.
