Hi! I am starting a 10 gallon aquarium. I feel as though I have a pretty good grasp on the nitrogen cycle and how to cycle a tank (I've done a lot of research), but I can't tell if I am doing something wrong. I have had my tank running for almost two weeks. On the 19th I used Dr. Tims ammonium chloride to spike the ammonia levels. They went up to about 4 ppm, but nitrites were still at 0. On the 24th, after browsing a ton of forums, I decided to do a water change and bring the ammonia levels down to about 2 ppm instead. Now it is the 29th, my ammonia is still at 2 ppm but there is no sign of nitrites. I have been using prime to detoxify the ammonia, but I don't know what else to do. Shouldn't the nitrites have formed by now? I am using the topfin 10 gallon aquarium, I do not have live plants, and my pH is at 7.8. Please help!
