I will have to agree with above post. 
I would sugest using Marco rocks as your dry rock (a very porous rock) then seed it with few pieces of live rock for a more diverse life. Few weeks later and its live. 
I always suggest for those buying the rock from me to have a 30% live rock(smalle to medium piece) spread across all the dry rock  untill ready then rearrange the rock to your liking.
