ok so I have just gotten some dry rock and want to start playing with it to get some ideas for how i want it to look. some of it is new rock and some is dried rock. the dried rock i know will start the tank to cycle once i put it in since there are dried stuff on it that was alive. question is will it be ok to put this in and then say add the live rock later this week. next question is im not adding any fish anytime soon till i get the rock all in place. so if i add some live rock next weekend and the cycle starts will it hurt to add some more live rock in a couple weeks. is it bad for the live rock to keep cycling?
