So I told him when I start my 24G up I want to use dead Hatian becuase its only $3 a pound. I asked how long it would take to grow Coraline algae becuase that's when I think Live rock truley becomes live. He said it would just start to begin growin in about 7 months!!! So that's what I think is how long it will take your dead rock to become live.
Coraline can start to grow within a month if the conditions are right.
HOWEVER, Coraline growth has nothing to do with the status of the "live rock". The "live" in live rock refers to living bacterias and other living organisms that inhabit the pores and crevices within the rock. If you plan to stock your tank with dead rock, I would plan to add a few good quality live rocks to seed it. Also remember, the LR is the cornerstone of your filtration. It would behoove you not to skimp on the rock.
