Live rock : can we make one?

[flashout]

Hi, I want to get more info about live rock as what I have read over in the internet are confusing.

Live rock can be easyly purchase in most LFS, selling around RM 8.00 (USD 2.00) per kg. What it is actually?

From the internet, it said that its prefer that we "cure" the live rock before putting it inside the tank. To my understanding, during this process, we kill everything inside the live rock, then put it in a new tank for 2 - 3 weeks, so that new micro will grown inside live rock. It is true?

Then, does it mean that we can create our own live rock by putting rock/ coral/ lava rock inside the tank?

live rock are the rocks harvested from the sea. during the transportation/shipping, there will be significant die-offs on the rocks (bacteria as well as organisms), so usually curing is subsequently done, i believe, to allow the die-off to finish so that it will not pollute the water when u put into the tank. Curing does not kill everything inside the live rock. Eventually the surviving organism will replenish themselves.

And yes you can create your own live rock from coral rocks, but it will take some time for the organisms from the existing live rock to spread. HTH

Thanks for the explanation.
