Small GFO Reactor suggestions - AquaMaxx vs. Innovative Marine?

[Quiverfull]

I would like to run GFO in my 20g sump (37G cube DT, total water volume ~50gallons). Need a relatively small footprint (4 inches square). Any suggestions? I was looking at:
1. Innovative Marine MiniMax pro (https://www.bulkreefsupply.com/auqa-gadget-desktop-minimax-pro-media-reactor-innovative-marine.html)
2. AquaMaxx Fr-s ()
3. AquaMaxx Sigma-2 in sump (https://www.marinedepot.com/aquamaxx-sigma-2-in-sump-media-reactor)

Anyone using any of these with GFO? Any other suggestions?

Thanks,

Greg

Aquamaxx makes good reactors.
