Cycle Question

I just added the live rock to start cycling my new aquarium about 24 hours ago and have not experienced an amnonia spike. Is this normal? If so, how long until I see a spike?
Tank is 40 gallons with 30 LBS base rock and 6 LBS of live rock that was just added to start cycle.

Should only take a couple of days, what is your water circulation like?
You can always use the shrimp method, that otta kickstart your ammonia.
:confused: I'm a bit confused, do you have a 40 gallon tank or a 35 gallon tank?

Its a long acrylic tank, and I always thought 35 gallons until I went and bought RO water for it.

if you have the funds add some more live rock so you dont have to worry about curing it seperately later.

get uncured live rock too... there will be more die off from the rock which will help kickoff the cycle too....

I would have to disagree on that. If the rock needs to be cured and is in an "uncured" state then there is die off, rotting, decay that is going on. If you have to cure it then it is going to spike with ammonia, nitrites from the die off. You will need to cure this rock for a more stable platform in order for it to support more life again.
Your best diversity of life is to have fully cured rock straight from the Ocean.

Disagree if you will...
Cured rock sits in someones elses vat or tank and the inverts alot of the times will evacuate the rock.
As for "cured" rock straight fromt he ocean floor...don't believe there is such a thing...once the rock is exposed to any amount of air, the die off will occur...now if one was able to keep the rock in the ocean water transferred to your tank in the same water...then possibly your idea of cured rock straight from the ocean would be possible...but we all see how that just isn't likely to happen...
Additionally...in regards to this particular thread...the individual asking the questions is in fact cycling his tank...

Either state there is live on it and in it, pods, worms...etc.. Mostly they need to repopulate themselves...agreed.
Wouldn't it be wonderful to get it straight from the ocean though? But right not likley.

interesting... fully cured rock straight from the ocean...... that one i dont understand...
what i understand, is rock straight from the ocean is uncured... has lots and lots of life.... Once taken from the ocean, it must sit in a holding tank where there will be much die off since a small tank can only provide an environment for a certain amount of life. Once enough die off occurs, the amount of life left can then support itself in a tank environment. when this happens, rock becomes cured.
for cycling purposes, decomposition of dead organisms creates the ammonia needed to kick off the cycle. Be it with damsels that pee or die, a raw shrimp that decomposes, or life on a rock that dies, decomposition must occur to kick off a cycle.
In a new tank, without any fish or life to worry about, getting uncured rock makes the most sense. There will be plenty of die-off to create a ammonia spike to start the cycle, and during the cycle, the rock will cure itself (although it may prolong the cycle since things will die off continuously during the cycle). and uncured rock theoretically should be cheeper.
It is more important to get fully cured rock (less chance of die off) when adding it to a tank with fish, corals, etc because you Dont want the die off to create an ammonia spike and kill the rest of your tank.

On one of my pieces of LR there is a green patch of macro algae hairs. Will this be part of the Cycle Die Off?

Rock straight from the ocean floor would be considered cured if it was never exposed to air from the ocean to inside your tank...
There would be no notable die off, so therefore it would be cured..
That would be a cool thing to be able to do Thomas...I suppose if we all lived in the Marshall Islands, Fiji, Tonga or wherever...we may be able to do that...
I wonder if moving to Tonga, becoming a beach comber/bum just to support my marine hobby would be a signal of issues within??

i agree with your statement but only partially....
yes, provided that we can supply an equivalent environment when we move a rock to a tank without much disturbance, there will be less die-off (i doubt there will ever be no die-off)
And no, there is alot more to it than just exposing rock to air. The rock had become balanced to an environment of significant water flow, much more than we can ever hope for in a tank, significant nutrients, which we may think we are adding, but most likely overdoing it on some of them, and under doing it on others, and other life that either the rock feeds on, or feeds on it...and lighting... well.. there is just no way we can provide the right type of lighting, no matter how much money we spend on lighting.
In other words, there is no way we can provide an equivalent environment for a rock that has been plucked from the ocean floor, and therefore, there will be die off, even if you moved to fiji and kept the rock in water the entire time...
