adding 80lbs of LR-with coral!? (edit)

[jennytheleopardgrouper]

I'm getting 80lbs of LR soon, and they're just covered in mushroom coral. They're also coming with some other coral that aren't attached...Now, if I get a spike, will my coral die off? Should I dump in some Prime with the rock, and if so, how much? Or should I just do some water changes and keep testing? I have a small quarantne tank (10 gal) that I'm planning to throw my fish into (green chromis) and I was thinking I would throw those extra coral in with them, until the main tank stabilizes. Any thoughts? Thanks!

edit- The rock is from an established tank about 3-4 years old. The trip home should take about 4-5 hours, and everything will be transported in rubbermaid containers with plenty of water. Does this change things?
