Water Why When

[dragonfly_sg]

I came across a couple of posts in this forum of aquarist advising newbies (like me) to let newly prepared saltwater (made with artifical sea salt) lie for a day or more before introducing life stock. Can someone explain to me why is that neccessary? Isn't water made today same as water made yesterday, assuming it's a bare tank with a current making pump? Or when is recommended period to rest the water?

If I lay my tank with sand, made the sea water with artifical sea salt and let it sit for a day. After a day, I put in alot of LR from an established tank and hook up a good skimmer (I think they call this a berlin system ?). Can I put in life stock immediately after I done the above? I would guess it would be possible if done incrementally. If your answer is no, I would like to know your opinion.

Lastly, if I collect highly mechanically filtered seawater (assuming no heavy mental and toxin) and pump it in a barrel for 2 weeks without circulation, do you think the water can be use in a marine tank after that?

These are some questions thats bugging me and I would greatly appreciate it if someone can help me understand the science in all this. Point me to a website or give me some key words, to start me search would also help.

Thanks in advance.

P.S. There are more questions, but they are evading me at the moment.

You need to read up more. search thought the forum on Cycling.. you got you facts all wrong. Getting your water and live rock source from an established tank or not doesn't mean you can just put LS the next day. You need weeks and you need to measure all your Ammonia, Nitrite then Nitrate during these initial stage.

I have been reading And I do have a little experience in keep freshwater and planted.

The objective of freshwater cycling is to establish Nitrifying Bacteria, isn't it the same for marine? Are there additional objective which I should be aware of?

If I have a new tank with only sand (sterile) and 1 day old water from saltwater mix, I should have no NH4, NO2 and NO3 other than those coming from PUB. Cured LR from an established tank will have the required bacterial to perform the bio-filtration needed, assuming they don't die en mass in the new tank (which I would like to know, if anyone experience doing that. In freshwater it's not a problem if the water params are similar. ).

Incidentally from my understanding, if I don't provide an immediate source of ammonia/nitrite to the Nitrosomonas and Nitrobacter will start dying as they're without their source of food. Can anyone confirm this? Therefore if i don't start putting fishes in immediately, then the effort of having LR is wasted as those bacteria will start dying? The anaerobic guys will probably last longer because of PUB's good grace and the decomposition of the bacteria in the LR probably start a mini NH4 spike and some nitrifying bacteria will survive. But in a longer period without import source of NH4, it'll slowly go down hill. When I am writing this, it seems strange but logical, any comments?

The reasons I asked these questions are two fold, firstly I am very interested in the science of all this and secondly I want to have enough know how, to set up a healthy marine tank within a shorter period (3 to 4 days). I know everyone will propose a slow start with 3 or 4 weeks of cycling, so I am interested in understanding whats suppose to happen (within the tank) in that period. And if there are work around.

I have a pretty good understanding (in theory) what should happen, but I am sure I still don't have the complete picture. By tossing my idea in here and having experience folk shoot it down (which I will try to defend with theories I know ) hopefully we can learn something together.

The thing I am most curious to know is the need for the saltwater (from salt mix) to rest for a period before introducing LR or LS, I encounter this statement on a few forum and I am pretty sure there is a good reason behind it, if someone explain or point me to any write up, I will be most grateful. I have a nagging feeling there is no short cut for this one

Well why we need to stand is that some cured liverocks got little critters starting to die and ammonia is increasing.If there is no critters then if you want to start you will need to put in market prawn meat to start cycling.If you jus put in a fish let's say a clownfish.It will die cause of no bacteria and ammonia starting to peak.That is why we need to let it stand and feed the bacteria.A lot of people when starting marine buy uncured lverocks to feed the bacteria and let it establish or feed it wif pieces of prawn meat.I just keep on dumping fish food inside.But the problem wif fish food is taking long long time.Guess you buy uncured LR from Reborn cause their stuff got a lot of critters will die.
