To keep things simple...Awesome, thanks! That was my single biggest question, the exact definition of "cured" live rock VS. "Uncured" live rock. Please make sure I have this correct:
CURED rock, is rock harvested by a supplier, which has sat in holding tanks for X weeks, in which a certain amount of die-off has taken place and reached a point at which in those tanks there is no further die-off. When this same CURED rock is then shipped to you, there is additional die-off from it being out of water for X hours or days. This rock may then need to go through another mini-curing, in your own personal tank, while the die-off associated with the shipping decomposes. Inside your tank, once it has reached a point where there is no additional die-off, it is fully CURED. Is this correct?
UNCURED live rock, is rock that has been immediately harvested and no time for the initial die-off has been allowed to take place. Placing this into your tank will result in substantial die-off, and all the mess and odor that may involve. Is this correct?
What do we call formerly live rock that is so depleted of life from being out of water, shipping, abuse, etc, that is is virtually "Dead" and has no value for a tank until it is seeded with other cured live rocks? I see some live rock that looks basically dead in comparison to other rocks that have plenty of green and purple and little creatures and things. I would assume the rock that looks to have more life and exponentially better to use in the tank?
My understanding of CURED rock in relation to the CYCLING process is that it helps the process along, but is it necessary? Would it be better to cycle a tank without live rock, and then add live rock in, and therefore create less die-off in terms of the creatures and microbes on the live rock? Or does a uncycled tank have no effect on live rock? I just don't want to spend $300.00 on live rock which I place in the tank in the first few days, just to have it all die-off and become lifeless.
What do we call dead rock (like something found in my yard and boiled) which has been seeded with live rock? Is this now considered live-rock?
Thanks for all the help.
Cured Rock - Rock which has gone through the cycling process and is does not have life on it dying off, acting fully as a natural filter....no odour..
Uncured Rock - Rock which needs to go through a cycle, had dead or dying matter on and in the rock, smells bad.
Dead / Base Rock - Rock which has been left out of water to dry out, effectively dead, no life, no decaying matter or brand new base rock, commonly ocean rock, which has not been in an aquarium yet.
Cured rock, really does not have a relation to the nitrogen cycling process, per se. People simply use un-cured live rock as a means of providing an ammonia source ( decaying life matter ). This ammonia source can also be provided by a raw shrimp / prawn or pure ( 100% ) ammonia.My understanding of CURED rock in relation to the CYCLING process is that it helps the process along, but is it necessary?

In my opinion, its better to cycle the tank with all the live rock already in there, as this will save any mini-cycles from occuring when you do add rock "after" the cycle has completed ( which is a common occurance ). Live rock is pretty hardy, in my opinion. Your always going to get a small portion of die-off when you add some live rock, but, that small portion will very quickly become live again, its certainly not something to be concerned about.
Hope that helps.
