First, I would like to apoligize for my ignorance. I bought live rock from marine depot live and when it came I was suprised that my live rock was just that one 11lb piece of live rock. I did the salt water bath and put in my 6g nano cube. It has been in there for about a week. I was wondering if anyone has any advice about breaking a piece of live rock? Specifically, when should I break it into smaller pieces? What should I use to break it- I am assuming a hammer and a chisel? Lastly, will this have any affect on the cycling or the "live" inhabinents of my rock? Thanks in advance.
