re: Just got back into saltwater aquariums. got sick deal

I never used sand or mud in my refuge. My train of thought was I wanted as much detritus as possible to go into the refuge for the macro algae to use. I would not put sand there because I could siphon out as much detritus as possible from the refuge....it was easier without sand. As far as Cheato algae, you got me on that one.
