Live Rock What to Do??

[saltyreef]

Hello, bought some live rock from a guy today, it is still in his aquarium. I don't have my tank set up as I am in the process of moving. What can i do to keep the rock alive and healthy without my tank for a week or so. Would mixing up some salt water in a rubbermaid with some power heads do the trick??? thanks guys, p.s. there is 100 lbs of it
