I also agree on the sand. Buy dry and see if the LFS
will give you a few hand fulls from an established reef to see it. My LFS
has never had a problem doing this for me. Also, whn buying LR
, see if you can find some Florida or Carribean aquacultured LR
. It does not come from natural reefs and is loaded with life. I beleive liverockreef and tampabaysaltwater both sell it.
