I am following instructions on the fishless cycle which I started on 2/27. I added the initial ammonia to increase the level to 4 ppm. After about 10 days it dropped to 1 ppm so I added more ammonia to up it back to 4 ppm. The ammonia is dropping again but there's no sign of any nitrites. Why? The ammonia level is dropping. It's a 20 gal freshwater tank heater up to 86. API tester. Am I just being impatient? I know it takes 4-6 wks for the process but I thought when ammonia breaks down nitrites start to form.
