Need help with cycle.

[alex07]

Hey all, I have 12 gal with a 50w marineland heater and ac50. So far I have 3 lbs of live rock, 10 lbs dead haitian rock, 2" of pfs and added 2 small pieces of dead haitian rock in the ac50. Hopefully by next week I can add the chaeto in the ac50.

So I started the fishless cycle on 10/31/11. On 11/3/11 I decided to add a fresh dead shrimp to speed up the process.

So here is where I need the help, My ammonia started to drop yesterday and my nitrites have been off the chart for days.

Am I missing anything?
Do I need to do a water change to bring my nitrites down?
Do I need to redose ammo to bring it back up to 4?

My water parameters have been the following.

11/3/11 - added the shrimp a couple of hrs before testing
Ammo: 4
Nitrite: off chart
Nitrate: did not test
PH: 7.8
Temp: 80

11/4/11
Ammo: 4
Nitrite: off chart
Nitrate: 10
PH: 7.8
Temp: 80

11/5/11 - got a foul smell from my tank so I replaced the shrimp with a fresh dead shrimp.
Ammo: 4
Nitrite: off chart
Nitrate: 10
PH: 7.8
Temp: 80

11/6/11
Ammo: 1
Nitrite: off chart
Nitrate: 10
PH: 7.8
Temp: 80

11/7/11
Ammo: .50
Nitrite: off chart
Nitrate: 10
PH: 7.8
Temp: 80

Ud say do a pwc to bring your nitrates back to a readable level then redose ammonia. You need to have the ammonia to feed your nitrifying bacteria conies to help them build.
That should help you get back in check!
