I just started my tank up 5 days ago, with live rock I purchased from local lfs. I just finished my first test today and my results are.

PH= 8.0
Nitrate= 10
Nitrite= 0.2-0
Ammonia= 0
Alkalinity= 200ppm

I just want to know if im on the right track? From what I've been reading seems to be good numbers for a tank to be running for only 5 days!
What do you guys think?
I know that the PH is a little low but the SG is at .022-.023, any suggestions?

Could this thing be close to a finished cycle?

im not a marine specialist but i would suspect that this tank is no where near cycled

From what I understand, it will depend on the nature of the live rock.

Did you get pre-cured live rock? If so, have you been feeding ammonia into the tank at all?
If the answer to both is "yes," I think you're pretty close, but I'm not positive.

If you did not get pre-cured live rock, it may be building up to a big die-off (the curing process), which will dump a ton of ammonia into the tank. This ammonia will then feed the surviving bits of nitrifying bacteria (and other clean-up organisms in the rock), which will fully cycle your tank.

Yes, the rock was precured. And I havent been adding any ammonia.
Im in no hurry for fish or anything, Im just curious to know if im on the right track. I forgot to mention that I have also added Carib-sea Arag-alive to the tank and its suppose to help with the cycling process.

But, should I be adding ammonia, or should I wait for the die off to happen to create its own?
Cuz if I don't feed it any ammonia, wouldn't it go threw a die off stage? its Not that I want to let it die off, but witch is better let it go naturally or add the ammonia?

If the rock is pre-cured, there won't be a die-off (if I'm getting this correct. Hopefully agsansoo or one of the other marine folks will come around and correct/confirm what I'm saying).
If it's pre-cured and you don't feed it, there will be a die-off, but it won't necessarily be good. By this point, all of the weak stuff that would die off no matter what should be gone. All that's left is the stuff that you want in the tank (okay, maybe there are a few unwanted hitchhikers, but we'll deal with those if they show up), so you want to keep them alive and growing by feeding ammonia (or just fish food) into the tank.

Anyway, if you dose the tank with ammonia, and then test it the next day and have no ammonia, you are, definitely, close to completing the cycle. If that happens, all you're waiting for is to be able to dose the tank, see no nitrites, and you'll be good.

Seems to be doing fine. Give the tank a little longer and just keep testing to make sure everything is going like it should. Yeah your pH is a little low, try to bring it up 8.3 - 8.4. Other than that you're doing fine, have fun with your new tank.

dont add ammonia , just add food and this will help your cycle did you have any traces of ammonia ? if you have precured rock you will get things die within the rock and give you a cycle ,, it can take only a few weeks to cycle pre cured rock so from above you are not far off just keep testing then get your nitrates down before you add fish or corals ,you should be able to get down to 0

Thanks for all the information!
I went out and looked for some pure ammonia, and what I found was a bottle of Roto Ultra ammonia. It dosent list the list the ingredients, but on the ont it says 10% ammonia 300% stronger than household ammonia. I dont know if this is ok.

So, I placed a small piece of raw fish and left that in the tank till this morning. I then tested the ammonia level and im now getting a 4ppm reading. Boy the fish started to smell already, so I removed it. Also I do notice today that im getting crud all over the tank glass. I assume this is from the bacteria?

the crud is probley from the decomposing fish ,,if you ammonia levels drop and you get a no3 reading and no ammonia reading then you are cylcled
