Carpet, Hardwood, or Crushed Coral?

[Mikey B]

New Guy again....question of the day to my reef friends in Calgary.

When I built my house it was carpet vs. hardwood.

Now that I'm building a salt water aquarium its sand vs crushed coral, and add to that the live-sand angle.

I want to work toward having a little of everything in my tank as time and experience permits....a few fish, a few corals, a few anemones.

What would you put on the floor of a new 120 Gallon Fish House?

Thank you!!

Mike
