Fluidized bed filter

What's the best media for a fluidized bed filter?

Sand. The kind they sell made specifically for the BFB models. I have tried many different media in these filters and only the stock sand and Quickrete media sand worked well, didn't clog on backsyphon (power down on pump) and remained fluidized.
