Your fine, if the tank cycles in a day to a month as long as it has gone through its cycle. I to started with base rock and would advise to dose Microbacter 7 once a week to help the biological filtration out. Just don't stock to quick.
Funny you mention microbacter 7, that's what I use. As far as rock goes, aptasia, bristle worms, and mantis helped me make the decision to use Marco rocks.
