I just picked up normal dry sand and the inexpensive rock from A.Concepts. No need to get special "live" sand IMO when you will seed it your self. Arguably, it
could help your tank cycle faster, but why rush

The rock at AC was priced by how "cured" it was. I didn't want any hitchhikers so I killed everything anyways (would have gotten dry base rock if I could). The bacteria and pods were seeded into my tank from my other tank frags and macros.
