So in reading a couple threads recently - people talk about 'live rock' yet seem to mean completely different things. What do you think best describes what the term 'live rock' means? To me there are many different kinds of 'live rock' 1. Live rock taken directly from the ocean - shipped overnight - containing many creatures, algae, etc. (this is my definition that I think of when I think of 'live rock' 2. Rock as in number 1 that has been soaked sometimes for weeks until all of the dead things have decomposed - the ammonia from which would have probably killed most for the living things on the rock in the first place. But contains beneficial bacteria 3. Rock that has been 'cleaned' all living things removed - and put in tank to cycle. The reason for the poll is there is a debate about whether 'dry rock' or 'live rock' is best for starting a tank. The way I see it - there is no real difference between 'dry rock' and the rocks in #2 and #3 above (or at least I can't see the reason) - What are everyone's thoughs>?
