How Is My Cycle Going?

[RIDavid]

I have been doing a fishless cycle for about a week and a half. I brought the ammonia up to 4ppm 2 days ago. Now it is back to about 0,Nitrite is over 5ppm,and Nitrate is up around 100ppm. I just brought the ammonia back up. Should I be concerned about the other levels?

Not at the moment, no.

If you find your cycle stalls, you may need to do a water change to reduce the nitrite and nitrate, but don't worry about it yet

Thanks,how do I know if my cycle stalls? I have done a couple part water changes.

A stalled cycle just means it's stopped, so you'd stop seeing a reduction in the ammonia.
