Do you mean you don't think HE will give you live rock or you don't plan on getting any at all? That would be kind of a shame!
Live rock is not only gorgeous, it makes cycling an aquarium so much easier than you can believe!
I got some water from my friend when he did a water change, and it had about 0.2 ppm
ammonia in it (must've just fed them or something). I placed about 5.5 pounds of cured live rock from my LFS
into the 10 gallon aquarium (quarantine), and gave it about 3 or 4 days...the ammonia was gone, the nitrite was nonexistent, and the nitrates were up just slightly. I put a fish in, and have never seen ammonia or nitrite again. Using the live rock, I cycled my tank in less than a week and didn't have to bother with the "shrimp method."
