Adding more live rock

[Twisted_blenny]

My tank has been up and running for almost 3 months now and is doing great I was wondering if I added more live rock would it cause my tank to start cycling again and hurt my fish? Also how soon can I start adding corals

It depends. Sometimes adding live rock can start a mini cycle. It's a risk you run. You lower that risk substantially if you keep the new rock wet while transporting it (covered in a saltwater soaked towel or newspapers). Also, adding it a little bit at a time rather than a whole bunch at once lowers the risk of a mini cycle occurring.

You can add corals whenever you want. :)

You could add dry rock, that wont hurt anything and its much cheaper and in a few weeks it will become live rock

My favorite place to buy dry rocks is MarcoRocks Aquarium Products
