Had an "aha" moment looking for ways to DIY a filter sock holder for my sump and figured I'd share since I haven't seen it anywhere.
I used a styrofoam block to hold up the plastic ledge of a filter sock within the chamber. Styrofoam is impossible to sink, pretty much free, and I'm assuming is aquarium safe since 3D backgrounds are made of them.
You can also make holes in the styrofoam to fit the filter sock holders similar to aquaponics systems:
