Cycling timeline?

I have a 10 gallon tank I set up at the end of the summer. I've been doing a fishless cycle, seeding with raw shrimp. I am running a top fin 20 gallon filter with a small amount of peat in stocking inside the pad. I also have some of those biofilter things- high surface area balls that give a good place for bacteria to colonize (I can't remember their name, sorry).

It's been 6 weeks today. My ammonia has been at 0ppm for several weeks, but nitrite is still off the charts. I'm using API test kits, which only read nitrite up to 5ppm. I'm still seeding with ammonia. Also, I added a considerable amount of plants about a week and a half ago if that matters.

Is this how long it's supposed to take? Whenever I read threads here about people setting up tanks it seems like their tank is magically cycled without fish in a couple weeks, even without using someone else's cycled filter media. How many more weeks can I expect to have to wait for it to cycle? Is there anything I can do to speed up the cycle other than using cycled filter media? It's been so long and I'm tired of looking at a fishless tank :( It's so hard to be this patient!
 
What is your nitrate reading?
 
Nitrate right now is 5ppm. It was a bit higher (between 5 and 10ppm) before I added the plants.
 
I am no expert. I did a fishless cycle and from start to finish it took just over eight weeks. I was adding amonia each day to a level of 4 or above. And the level would go to zero in 24 hours. During this time the nitrite level stayed high. Finally, I saw nitrates begin to increase. Then I saw nitrites drop. I saw one incidence of a bounce in the nitrite level, then they the nitrites went to zero. At this point the nitrate level was about 80. I did several 70% water changes and the nitrate level came down to the current of 10.

The nitrite phase can take a very long time. If it is that high meaning over 10ppm a water change is probably a good idea. You will never need to process that much nitrite. You could be waiting a very long time.
 
If seeding with mature media isn't an option, I would suggest buying some live plants. Pick up a few hardy plants like anubias and add to your tank -- plants process Nitrogen wastes and will also come with some of the bacteria you need.

Good luck!
 
How long is a piece of string? There's no predicting how long it will take without an initial seeding of bacteria.

This is so odd. I never see nitrites in my tanks when cycling. I was starting to wonder if they really exist. :)
