Cycle finished ???

[luisedumuller]

Hi Guys,

I am running the cycle in my fish tank fro 12 days now and apperently my cycle is close to finish.

I didn't have any huge spike in Ammonia, Nitrite or Nitrates.
Is it possible that my cycle did not even started ?

It is a fishless cycle and i am using live rock. Please have a look at the measurements:

Thanks in advance for your help !!!

I forgot to mention:
I am using RedSea Test Kit.
Diatoms are starting to show up

If the rock was fully cured you may not see a cycle. You can always throw in some fish food like your feeding fish for a week and if the ammonia doesnt rise your good to go.

Agreed. If you bought live rock from a LFS that went straight from there established tank to your tank, your cycle will most likely be very short. If you bought your live rock online, and had it shipped to you, I'd do like shifty says just to be sure. I've purchased live rock from the LFS and never had a cycle. I've also bought 60lbs of live/fully cured rock online, and a week later my ammonia was off the scale. I'd drop in some fish food and let it brew a week just to make sure.
