I would get dry/base rock, since it is much cheaper, and then a few small pieces of actual live rock. I would order about 50 pounds of Pukani Dry Rock on www.bulkreefsupply.com
and then pick up maybe 5 pounds of live rock from your LFS
. Pukani looks natural, is cheap, and it does not weigh very much.
