I'm not sure. I've always thought that if media is moving, then it's "tumbling" :-)

In BRS' video about Carbon & Phosphate and Reactors they show GFO "tumbling" in the reactor (at 2:50). They even say it is "tumbling" at 2:50 and 5:09 and 5:20. At 5:23 they also mention that, "all of the particles turn over a few times a day"

In their other video on just GFO they say it tumbles in the reactor at 2:46, 3:10 and 4:04.

But you are right in that it should not tumble the media too vigorously.
