Tank cycling?

[pisces01]

We have a 108g tank with 110lbs of lr, 3 inches of cc. The lr was cured (I think?)...well, it was at the lfs for about 2 weeks before we brought it directly home and added it to the tank.
My question is, will this be enough to cycle the tank? Is it possible to predict by the above info approx how long until we see an ammonia spike? We added the LR last Saturday and there has been absolutely no movement in the ammonia levels. Actually, I am beginning to think there is something wrong with the test (or me!) as its not even given us a zero reading yet.
Any input??

There is no limit to live rock but if you want to add more do it now. If the lr was at the lfs for 2 weeks it is not cured it usually takes 6 weeks. CC isn't the best subsrate eigther.

Actually, I was wrong, we have Aragonite for substrate. Last week we threw in a cocktail shrimp to get the cycle going. Only left it in the tank for a day or two then took it out. We are still not seeing ANY Ammonia, Nitrites and obviously Nitrates. Am I just being impatient?? Its been two weeks!!
Feedback, please....

Add the shrimp again and leave it in the tank. Test every other day until you start to see ammo. Two weeks is too soon to tell if your cycle has begun. I am not very familiar with using raw shrimp to cycle a tank. But I do know that after a day or two is too soon to remove it. HTH--Bob

We also thought that instead of the raw shrimp, maybe a few Green Chromis damsels They would definitely be more intersting to watch
Would this work?

Your LR was cured, thats why you didnt get an ammonia reading in a few days. I recommend purchasing a hardy fish you really want and a small bag of Natures Ocean LS if you can get it, I believe your tank wont cycle when you add them because it has a small bacteria colony already established.

I agree with BurnNSpy, sounds like your LR was cured. Add a small hardy fish and wait a couple if days to test. Patience is the key. We would all like to load the tank up the day we get the water, but waiting helps to insure success.
