The only measurement of bacteria we have are the levels of ammonia and nitrite which unless I've misunderstood something, have remained at 0ppm throughout the 30ish days the rock has been removed.
This means that the beneficial bacteria in the tank is enough to match the current bioload of the tank.
Adding the rock back in is in no way shape or form adding bio load into said tank.
Since the bioload of the tank directly limits the amount of beneficial bacteria in the tank, adding rock won't effect the cycle in either a negative or a positive way.
if there is something I'm missing, please enlighten me.
