tank maturity question

[temec_luver]

ok so i i have a question.... i upgrades from my 2 other tanks... one was 4 months old(12g) one was 3 months(2.5g)
the rest of the rock i got was out of a guys tank and had been cycled and was in there im guessing a year.... i do have some coraline growth but my urchin eats most of it...

since my rock was all from previously established tanks does it add to the maturity(age) of the tank? it gave me no cycle what so ever and i have lots of pods

[mr slinky]

dont matter how old the rock is (maturation) the water needs to be cycled going in there!!

[temec_luver]

i used all the water from my oldtanks plus some nsw i bought from the lfs

Depends what you mean by maturity. If you've got a lot of cured rock and a low bioload, you might not see much of a cycle. However, that doesn't make the tank mature -- for "maturity" (imo) you need to wait for a healthy population of 'pods, benthic fauna, etc. That stuff takes time.

Just by adding rock that is mature, it wont make the tank mature.

ok yes i have a low bioload (one fish) im just wondering if it was mature coral and invert wise... all my params are good ammonia=0 nitrite=0 nitrate=10 (on the decline just added macroalgae to the fuge

waittill the trates are down then you can add somting else. Just add slowly do not rush it.

that was a good thread. it was cool when EB was spending a lot of time around here.

There is something wrong with this statement.
Not sure what the meaning is, but if it means that water has to be cycled in any way, that is wrong.
worse, this is confusing nitrobacter cycling with longterm maturity.

all those rocks have nitrobacter established. unless you spike the nutrients to "re-cycle" the tank, you will not see any cycle, as the bacteria are handling whatever comes their way already.

furthermore, the "cycle" is not about the water. the water is the rinsewater during the cycle. the cycle is about the bacteria.
that's why you do a waterchange AFTER a hard cycle. time to change out the rinsewater for new, once the bacteria is all settled in on the LR.


and this whole maturity issue leads back to the BB vs DSB wars.
Following EB's mention of the "climax forest" concept if you will, there is a point where DSB's hit their peak, and are awesome. But due to the closed nature of our systems, the inevitable prrogression is from peak to eutriphication. this is where bacterial cementation, attrition of sandbed species and general siltation gum up the works.
This is about where I started pursuing the methodology of using periodic major disruptions to sort of keep resetting the eutriphication timer with the goal of maintaining an indefinite stability.
Mother nature's answer is to just keep adding sand, and the stuff below gets pressed/cemented into reefrock, so the sandbed critters just keep creeping upwards leaving the yuck behind. this keeps longterm stability in the top layer of sand via constant change.
Maybe multiple remote DSB's would work, replacing alternate ones alternate years, so never a brand new one alone and never one get old and crash.


The reality? juggling nutrients vs starvation in a BB is a trick. I'll get it going sweet for a year or two, then something goes wrong and I'll have a setback, then get it dialled in again. This iteration is the firat time I've tried minimal LR, so we'll see if that was some of my troubles: having too much LR in the system all this time.

I laugh, looking at this one rock of generic green paly's "moon polyps" that I have had since the beginning. How many times it has ridden out a crash . After the bad crash in like '92 (it was all about a dolomite sandbed, who knew ) they stayed closed for a couple years heh. Some day I'll get it all figured out. but then I'd probably be bored with it.

Frick-n-Frags stuck on that sand bed again. I think There is much more to tank maturation and the "climax forest" than the sand. The sand does act as a nutrient and toxin sink and this does cause issues latter, or right away such as hydrogen sulfide. Also, calcium carbonate may precipitate for a number of reasons-this may "lock in" or be effected byorganic materials.
However, there may be much more going on than this. I think this is getting off topic, but if your intrested in tank maturity issues, you might be this is agreat article by Julian Spring:

The sedimentation and cementation events rshimek describes do certainly occur...
