Even the best dry rock will not denitrify very well, if at all, in the first few months or longer. Therefore the NO3 will build unless you do substantial water changes.
Also, if the dry rock is previously used live rock, it's likely a time bomb for phosphates. PO4 will accumulate in the rock, and any life in the rock once removed from water will die off, causing a dry reserve of nutrients that once wet, will leech back into the tank.
