moving bed bio filter

[Harpo]

Good morning R2R

I see moving moving bed bio filters being used on fresh water. Could they be used in Salt water systems?

Thanks

Fluidized bed, yes they have been used in many applications including marine aquariums. I think they were a short lived fad in the recent past but they never caught on in popular use, and I don't know why that is.
