I'm a little over 3 weeks into my non-planted fishless cycle now and here is whats going on. About 2-3ppm ammonia is being processed out in 10 hrs or less and I'm adding daily. My nitrite peaked at ~ 5ppm about 10 days ago and has steadily declined and has been sitting at .25-.5 for nearly a week. Strangely, nitrate has been at 5-10ppm for this same time without shooting up. I've kept the water at a steady 85*F, ph has sat pretty well @ 7.8-8, KH is 5*, GH 9*. It seems to me I'm at that stagnant phase where all of a sudden everything will be zero and it will be done. What are your thoughts?
