Which pump for my reactors?

[CKI]

So I am gradually declining with vodka dosing and plan to put my 2 Phosban 150s back online and run GFO and Carbon. However, i have NO room in the stand by the sump. So this forces me to place both units in a closet next to my tank where my ATO is. My ? is which pump will i need to effectively tumble the media as needed. I'm figuring roughly 6ft from sump to reactors and then 6ft back to the sump. I think a MJ1200 will work on the GFO but not sure about the carbon. Any input would be great.

I run a mj1200 on the exact units. 1 with purigen, 1 with gfo and carbon. Both work great.
