bkcup, any sand added to your system will eventually become "live" live sand is simply sand, that has bacteria and other critters living in it. The bacteria comes from simply having life in the water. The critters come from either the
LR or from putting a sample of already
LS in your tank as Darb2 mentioned. If you have the resources, get your system set up and cycled, then buy 1 pound of
LS from 3 or 4 different
LFS or other hobbiests in your area. The best DSBs have a very diverse set of life in them.
