Definition of a mature tank

[hookedonreefs]

I was wondering. I keep seeing the term 'mature tank' and I would like to open up a discussion on it quickly.
Whenever I see 'mature tank' it is coupled with balanced chemicals, stable water conditions - stable Ca, Alk & pH etc.. It has led to to believe that these things make up the deifinition of a mature tank. I'm sure I missed things like pod population, and diversity of organisms, but what else defines a mature tank? I'm sure there's other little things that create a mature scenario - ie: having gone through certain algae outbreaks and other things I have yet to 'discover'.
The reason I ask is that water chemistry and diversity seems to be more of a tank husbandry and good planning. I feel I've done these things. I have stable water param.s I have lots of pods, and a good cleanup crew. But I'm still holding off on getting SPSs and clams because in terms of time, my tank is still 'immature'.
Can anybody help me with this concept. Am I correct or am I missing something?
Thanx

Kip - <B>you and your tank need to prove to yourselves that you can keep the conidtions ideal... even in the face of isolated problems</B>
I already have to work every day on doing this with my wife....
Now you want me to do it with the tank too!!!???? And the tank doesn't even .. uhh ... well .. you know ... in return!!

You totally just ruined this hobby for me! Now I'm going to go home and feel double-married! LOLOLOL!
Seriously though, you used another vague word - 'extended' What's an 'extended' period of time? I always make sure the tank is balanced for at least two weeks before looking to add anything in there. Usually this leads to nothing being too out of whack.
I did battle cyano. but I think that's common for an (here it goes) immature tank. I got it to go away, and it hasn't come back. I've had additions and all is going well. I'm now getting into fragging since everything is growing so well.
The whole time everything is 'balanced' (not including my marriage and the checkbook <-hmm is there something in common there) are you saying that I can start considering my tank mature? I don't think so only because it's only a couple of months old.?.
Now - don't get me wrong, I really appreciate both yours and mmmmsushi's input. I respect both of you very much for the information you've given to the board. I just want to make sure to clarify any rock-solid way of determining what a 'mature tank' is.
Comprende?
and - as always - thanx.
