I don’t know about others but I’m using a marine pure block and live rock underneath my chaeto. No sand or other substrate.

I put a 20lb bag of live sand & some coral rubble in mine, have cypress trees growing. I also have cheato & other macro algae in it.

Rubble Rock -- mostly because I read online to do so when I was researching fuges, and I wanted extra live rock.
