Fiji cube sump, and filtration

[Bob Escher]

I just upgraded after 8 years to have an innovative Marine 50 gallon internal overflow and a Fiji 24 Sump. After the sumo arrived I realize that there is no good place to put filtration. I can’t hang a reactor on the wall of the stand ( it’s metal and all four sides have a door) so I’m at a loss.
Any ideas

You can see if the metal walls are magnetic; glue a strong magnet to the reactor mount.

You can even run your media passively in a bag.
