I am wondering why I am not reading any nitrites in my fishless cycle? It has been 11 days since I first started it. I got the ammonia up to 5ppm on the 4th day. I was adding the same amount that got me to that level up until 4 days ago, when I stopped adding ammonia all together. I wanted to see if the ammonia level would go down at all. Well I tested on day 8 and the ammonia read at 2.5ppm but still no nitrite. I tested a day after and the color on the chart looked like it was in between 1.0ppm and 2.5ppm, but no nitrite I just tested again today and the results are the same as on day 8. Why would I have a lower ammonia reading but no nitrite? I am confused.
