You don't need much flow for these. I currently run two TLF reactors in series off one MJ1200 and it's almost too much flow. If you have a manifold with a small outlet you can dial down to 200gph or less, that should work.
My carbon doesn't move and the water flows through it and out to the GFO. The GFO tumbles very slightly.
