So I've only been at it for a couple of days. I added the ammonia about 2 days ago and at first it was around 5-6ppm and now it's at about 4ppm after testing today. I haven't added any since I started. Should I add more or just wait until it gets lower. I was a little confused at this point. I also just for the heck of it tested for nitrites but that was at 0ppm. I have live plants in there so I didn't know if maybe they were using some of the ammonia.
