Hi there - Hoping to get some advice and suggestions on my attempt to cycle a new tank using the fish-less method. I am on day 17 and have been adding ammonia daily per the instructions I found on-line. I have kept the ammonia levels at 3ppm daily - as of last week, the level drops to zero in 24 hours. My nitrite level is off the charts and I am also seeing nitrates (don't know the exact number, but they are present. I did two 10-15% water changes when I noticed this last week - but the levels are still the same. My PH level is also very low - i have added PH increase (not sure what brand - but it doesn't seem to work in increasing it at all!!) I guess in sum, I am wondering if this is progressing properly?? Should the nitrites be going down? Should I do another water change to get the nitrites down??? Thank you in advance for the help!!!
