Ok i see a few problem here.
1) how do you plan on supporting the bioload with no live rock? Not impossible but just asking how your planning to do this?
2) dead rock, is not live. Meaning it cannot function as a biological filter. It will need to become live first.
I highly suggest waiting to cycle the tank, and waiting for live rock. Otherwise you could be asking for problems that could endanger any livestock. Not a great idea to start off a tank when its not ready. Just my opinion.
