I have to disagree with just about everything NAS just posted.First of all everyone who has ever put live rock and sand into a tank knows there is a cycle without any critters in the tank and that massive amounts of amonia are formed from the die off on the rock starting up the nitrate cycle.In my opinion there is no such thing as buying cycled live rock from an on line dealer because it aquires more die off when it is shipped which sometimes takes 5 days out of the water before it gets to someones house.The closest you can come to real cycled live rock would be to buy at an lfs and transport it home in water.
The addition of critters to a tank brings on another cycle slightly less devistating and generally much shorter than the original cycle.
Make no mistake about it there is a cycle and it takes place long before the addition of any critters.
