I do not agree to the die off part, imagine if you lift your liverock out of the water for a few seconds or even minutes, I do not think there will be significant die off. Of course I do not know how fast is the transfer process, but how long will it take to move from one tank to another accross the room?

First, bacteria is a cellular life form, not even tissue grade, they are much more hardy then complicated life form, visible example will be algae, for those had algae outbreak before you should know what I mean, they do not get wiped out easily and reproduce like wild fire. They Even human were to go extinct they will not.

Second, their life span is very very short, from hours to days, thus so is their regeneration and reproduction capability. Such an amount of die off will not be a major impact to their population. Even you don't do anything to them they die very quickly and of course they reproduce before that.

Third, I think you are mistaken by the facts about anoxic and aerobic bacteria. Aerobic bacteria which dominates the surface of the liverocks do not die as long as the surface does not dry off. The more oxygen the more they thrive. Anoxic bacteria, which dominates the deep core of the liverock (low oxygen environment), will be killed if exposed to high oxygen environment. As it is deep in the core, it will still be wet, unless you are drying the liverock in an oven.

Fourth, The amount of nitrifying and denitrifying bacteria you need does not depend on the tank size or the water volume. But by the bio load. If the bioload is not increased there will not be much strain to the system. But I agree with you that he should not add fish so soon.

Fifth, the concept that "nitrate factory" does not harbour significant amount of bacteria is wrong. They harbour nitrifying bacteria, and lots of them, as it has huge pore size to allow oxygen to reach right to the bottom. But not denitrifying bacteria. Nitrifying bacteria colonise all external surface of solid no matter it is liverocks or substrate or bioballs. System without DSB or plenum system has negligible amount of denitrifying bacteria anyway. Thus exposure of substrate to atmosphere has little impact on the bacterial population. And a huge pool of denitrifying bacteria is not necessary in the sense that many people do without DSB and have sustainable tank, and as I said these tanks has no significant amount of denitrifying bacteria anyway. And lastly the term "nitrogen cycling" is refering to the establishment of nitrifying bacteria and does not include the denitrifying bacteria.

Sorry for the long post and hope that you didn't dozed off :paiseh:

Hmm...nd to take breaks in between to read else very bad for my eyes :lol:

I did a tank migration couple of mths back from a 3x1.5.1.5 to a used 3.5x2.5x2.5 tank tat has a sump filled with used coral chips (this tank has been in used for more than a yr until this fren of mine decided to downsize and let me have the tank :yeah: ).

I used back the same sump (untouch), same sandbed plus i top it up with new sand to 6inches thick. Cycled with abt 80kg of new LRs for 2mths. Performed 30% water change after cycling. Let tank run for 1 more week before removing abt 30% water again and this time transfered all the water from my old tank, together with LRs, corals, fishes....basically everythin from old tank go over to new tank.

With all water parameters tested.....ok. I had 60% of my corals tat die on me.

Now care to share which part of my migration tat goes wrong base on wat u have replied on ur eassy post. :thanks:

Wat i have mentioned in my initial posting is... thru the using back of all ur old media, used LRs,....etc to a new tank doesn't mean this new tank is going to be a 100% living environment for ur LS juz like the old undisturb one. As we r toking abt LS in our hands and being responsible in reef keeping. We need to go the extra mile of being cautious rather than hastily performing a migration base on believing. Tats y the test kits being sold r use for = to peform the necessary water test to ensure the condition r rite.

Ammonia > Nitrite> Nitrate> Nitrogen gas = the end product tat every reefers wanna obtain. But mostly reefers are stuck at Nitrate due to the fact tat there r no means of removing them especially in a new tank due to not having a denitrator, DSB, refugium or these system r simply too young to coupe. Juz take DSB for example, it takes at least 6mths and above to mature and during this period...wats the alternative way to counter the existin nitrate problem.> Thru dosin chemical solution and hopefully it do cause water unbalance. And having a cannister filter tat lack of maintenance will only contribute to more nitrate buildup and even having all the nitrosomonas and nitrobacter in the cannister filter but ultimately the process juz stop at nitrate. So on hand u r having nitrosomonas and nitrobacter in the cannister workin for u on the other hand the cannister is trapping debrities and causin nitrate buildup.

There are 2 types of person, those that chose learn n do it rite the first time and those tat chose to learn it the hard way.

I agree with jd_n.

though it only takes a few minutes to transfer live rocks from tank A to tank B during migration of tank, that doesn't mean that the parameters within the new tank are stable, or as stable as it was in the previous tank.

its like moving into a new house. you get the professional movers to come move for you into your newly renovated house. you may have spent a few thousand dollars on the renovation, but that doesn't mean you'll settle to the new surroundings immediately. some people even get stressed because the buttons of the lights are in a new arrangement, or certain elements of the old house is missing.

the same can be applied for a marine tank.

my two cents. (=

Tats y to minimise stressin out the old inhabittants. The least bit we can do is provide the least problematic water condition as close to the previuos tank as possible.

And all i can think of is to do a proper cyclin and perform water testin so tat when using back any used media with all the so called 100% survived nitrosomonas and nitrobacter, the least is tat they will be able to handle the new system with minimal affects on the water conditions so as to minimal stressin out any LS. ;)

too complicated confuse him..

weishun, u can go library to borrow some marine books..

they got simple 1-2-3 layman terms how the whole bacteria cycle..

with pic n everything.. u will get a clearer pic after that.

that's what I do read n read from books n surf webby...

Hmm... this is getting complicated here.... anyway thanks guys for the advises.. i will follow up on both your advises and see what happens to my tank. Thank you so much for the advises... cheers!!

My advise is simple..........standby more New saltwater,PH buffer & AZ-NO3, do a weekly water parameters test(SG,PH,NH3,NO2,NO3), if NO2 or NO3 increases, do a 20% water change & add in some AZ-NO3.

Meantime refrain from adding any more LS which is the toughest for me, if you can't resist the temptation, do it only if your NO2 is zero and NO3 is below 20ppm.

Lastly, custom make a sump and get a effective protein skimmer.

Thanks guys for the advises and the info that you've all provided. I haven been able to find time to log on to post recently. Hehe got some "ECAs" going on outside besides reefing at home. The information you guys provided was crucial to me. It helped alot. Thanks guys!
