    I am in the middle of cycling and the ammonia has finally dropped to 0 ppm. The nitrites are at about 5 ppm and I have also noticed nitrates. Will too high of nitrites stall the cycle? And should I dose more ammonia to feed the bacteria? I am concerned with the bacteria starving, but I do not want to have too high of nitrites.

    I would do a big water change to reduce the nitrites, maybe 2 back-to-back 50% water changes, try to get the nitrites down to about 1ppm, then add ammonia.
