The first kind of bacteria converts ammonia to nitrites. The second kind of bacteria converts nitrites to nitrates. How long does bacteria #1 take to die without ammonia? The reason I’m asking this is because I’m currently cycling my tank (since the middle of March) I should be done already but I’m not. In one point in time my ammonia was able to go from 4 ppm to 0 ppm within 12 or 15 hours. Instead of feeding 4 ppm of ammonia daily, I started to feed them 4 ppm of ammonia every 3 days to allow bacteria #2 to catch up for a week. Bacteria #2 was able to catch up and now it’s able to process all the nitrites down to 0 ppm within 24 hours. But bacteria #1 now takes around 1.5 days to process all the ammonia from 4 ppm to 0 ppm. Every time I do a water test 24 hours after adding 4 ppm ammonia, I get 1.5 ppm ammonia and 0 ppm nitrites. I know the #2 bacteria are still there because a few days ago I had 5 ppm nitrates and today they are around 20 to 30 ppm. Is there an explanation to this? Did half of bacteria #1 starve to death and died while I was feeding them 4 ppm of ammonia every 3 days? I only did that to allow bacteria #2 to catch up and because everyone seemed to do it. No one seemed to have a problem with it. But idk why I did or what happened.
