I have been cycling my 55gal with 10 cherry barbs going into week 6...ammonia 0.0ppm, nitrate under 5.0ppm but the nitrites have been lingering between 0.25-1.0ppm depending on water change schedule for over 4 weeks. I have not lost any fish due to daily water changes but is this normal to have to nitrites sticking around this long?
