GFO Tumble Rate

I just setup my media reactor with separate GFO and Carbon "chambers" for the first time instead of having them mixed and held in place, non-tumbling.
My question is, what is a good tumble rate for GFO?

I have a few choices, or you can tell me "something in between".

This is the minimal tumble (probably the best for my carbon with the most water contact to carbon time):

Here's the moderate flow rate:

Here is my heavy flow rate:

It should be noted that in the first two videos, the tumbling appears to be very localized and most of the GFO does not appear to be tumbling or even moving. It is only in the last, heavy tumbling, video that all of the GFO appears to be moving.

Let me know what you think.
 
If you could get a good tumble with the last lowered a little that would be good. GFO is hard so its not going to "dissolve" like carbon would. As long as your tumbling but not losing it out in the return, you should be good. Want it to increase in height about double as it is without flow, and that should create a good flow, tumble through it. It is like carbon though that you want good surface area contact and GFO that isn't moving isn't have good water flow contact. I run two reactors and replace my carbon more often than I do my GFO. I actually use a spray nozzle that you would use for bio-pellets, in my reactor, only because it creates a better spread of water up through the chamber. My reactors are from avast marine.
 
you just want it so you can see the surface moving, too much will grind lik brent said
 
Slowed it WAY down. Will post a new video tomorrow to confirm its good.
