So I have been cycling my tank for 42 days now and at day 39 I had my nitrite drop after a long, excruciating battle of trying to get them down. But, one thing I am confused about is that even after my nitrite drop I have 0ppm nitrates. For the past 3 days I have been continuing to supplement ammonia and my nitrites and ammonia are able to drop down to 0ppm in 24 hours. But I still have not seen nitrates (note that I have seen nitrates before earlier in my cycle, they just didnt sky rocket like I expected after my nitrite drop). Before my nitrite drop I was doing daily 30% water changes, but then stopped as soon as my nitrites dropped. I did this for 5 days. Could this be why I'm not seeing any nitrates now?
