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.
