Main consideration will be pest control. A lot of people start from dry only and seed it to avoid introducing unwanted pests.Hey everyone, I have a question. I have the option of either getting live rock or Marco ReefSaver shelf rock. The liverock is cheaper than the shelf rock... so I don't know if it's even worth getting dry rock anymore. I would appreciate some suggestions thanks.
If you are not worried about that, go with all live.
Ome more reason for using those shelf rocks is to be able toaquascape in the way you want and create your own structures. I assume this is not as easy with live rocks.
