HOB refugium

[marlinmero]

i was thinkin about gettin a hang on back refugium and figured id ask if its worth it and what to put in it? Sand or mud or both? if chatoe algae is the best thing or if there is something else. or even sum mango or shaving brush plants. More less just any information would be great

Sand and cheato will work great.
