Hang on Refugium

[DjPHILLLLY]

Does anyone have a decent suggestion for a hang on the back refugium for a biocube 29 that doesn’t require much or if any modifications? I really don’t want to do the back chamber again.

I use AquaClear HOB filters as refugiums on most of my systems: some unlit with reef rubble and others as macro algae refugium.

The AquaClear 110 on the 75G display is full of reef rubble with large pods & micro starfish.
