Adding Tang and rock at same time

No if you understood what L/Rock is then you would understand what will happen , I have posted a million times about the cycle of de-nitrifying bacterias . And thats all L/R is really a bacteria sponge , There are so many misconceptions of L/R and Sands benefits it off the charts.

But the bacteria we depend on can not be stored or saved up that rock it will have only enough bacteria on and in it to handle the amount needed to deal with the die off while it was curing to meet the demands placed on the water it was cured in . Then as they died off then the remaining needed to get stable and so it goes , Now at the end of the so called curing process then what do you have ? rock with a bacteria colony in a state of constant fluctuation form the time it was removed from where ever it came form months or weeks ago.

So when you add the CURED L/R it will still die off then rebuild the needed bacteria for the system it will be living in. The add a tang with its bio demand on the already slack system then you will wind up with a real spike and either kill that fish or all the fish. or cause a ich outbreak from the unneeded stress .. You can have a Olympic swimming pool for of tons of rock and sand and water with 1 little fish in it . Thats all the bacteria that will be present on that rock and in the sand that is needed just for that one little fish. But if you add anther fish then you will have a higher demand and they will come But its not a large of a shock as its far more volume of water but not bacteria .

I also have seen far more aquarium health issues since L/R became all the rage. Its totally unneeded in a tank I have never found a need for it after My first pure Berlin yrs ago never again will I use it....

And in this case I would not add them both at the same time tank will need a few weeks or month to recoup from the rocks addition then wait a few weeks and add the fish

 

Why would you add live bacteria at all ? Not to mention at double the dose to only have it to die off from lack of a food source , if you are not in a rush the bacterium will colonize to proper levels and the water will not cloud up from oxygen depletion from dead bacteria and or run any risk of any bacteria die off to throw the system in to the mini cycle..

 

There is a lack of understanding here. If you have dead rock, the bacteria will colonize it, if you have cured rock, all of the bacteria within the rock will not die off. Really "die off" is pertaining to all the other potential life within the rock (worms, feather dusters. eggs etc.) and some of the various strains of bacteria, of which there are many. The extra seeding of live bacteria is for the sand bend and to replace those that can be replaced. Rather elementary in terms of the colonization process but perhaps over looked or never understood by aquarists and is a sound practice.

 

Main misunderstand is L/R is all about the stuff on the rock its the bacteria that is all L.R was ever used for in the first place then it went to what it has living on it . Its the bacteria that was the whole logic and reasoning behind its use at first . all the live organic stuff came much later after some marketing ideas kicked in.
But the bacteria will seed and come in their own time to handle the ammonia and nitrite gasses , But as the spikes climb and fall so do the numbers of the needed bacterium like the Nitrosomonas they metabolize the ammonia into a less deadly gas called Nitrites that in turn are reduced into nitrates by the bacterium known as Nitrobacter's family and they are about the end of the line for aerobic bacterium..
Now inside the rock there are small numbers of anaerobic bacterias but they do little at all really and not what is in play here for this thread . so I won't get into much talk about them here

So at the end of the day when Nitrification occurs principally through the bacteria families the Nitrosomonas , Nitrobacter all you have to do is give them the needed time with a food source and they will rise to proper levels to deal with the daily demands add something new or remove something dead then they will react accordingly with their numbers . This is where the live organic stuff on the new L/R comes into the equation it will all dies off and pollute and tank causing a ammonia and nitrite spike and then the old established bacteria will need time to build up to break the added new demand down .

A good aqua-cultured L/R will have nothing much on it but bacteria and coralline and is shipped wrapped in damp newspaper and plastic bad never in water .. And smells like lettuce or celery with salt on it..Not like death warmed over ..

 

Wow thanks everyone---I think I will add 1/2 of the live rock--wait a couple of weeks--test--and then add the other half--wait a couple more weeks and then add the new tang. I have been adding 50lbs at a time after I cured it for 2 weeks (I buy it in 50lb boxes at the LFS-comes to about 2.85 lb that way and is very fresh as Tangster described it) always made sure the readings were at zeros before adding. I always understood bacteria colonies as Tangster said--Only enough to handle the Bio-Load. Maybe I have been lucky or maybe the extra bacteria on the new rock just died off to the appropriate level--sorry so long to thank ya'll I had to work late. Any other comments would be welcomed.

 

Adding live bacteria (even in established tanks) is tried and true........to each his own.

 

Thanks U.J. I did add Bio-Spiro Marine when I had just finished cycle.
