I was doing a 80-90% water change two days ago and I forgot to add in dechlorinater before turning on the filter. It was about a minute, maybe less, before I realized this. Today, my ammonia was 2.0ppm, my nitrites were 3.0ppm, and my nitrates were 5ppm before I freaked out and did an immediate 50% water change. Did I just kill my cycle? I added extra aeration and a heater to my water garden outside and that's where my fish are currently residing (I don't think they'd last very long in my tank at this rate). Do I have to wait to establish another cycle?
