So I just recently set up my 40g Nuvo, I set it up with cured live rock from the LFS, live sand and I bought my first bit of water from the store too. I have been using seed by Aqua vitro. So I set it up last Sunday, and on day 3, I had an Ammonia of 2ppm, but I had no Nitrates or Nitrites. The next day I still had an Ammonia of 2ppm but still no Nitrates or Nitrites. Then on day 6 I tested it again, and I had 0 Ammonia, 0 Nitrites but 1ppm of Nitrates. Then Yesterday, (Day 7) I tested it and I had 0 Ammonia, Nitrites and Nitrates. I yet again tested it today, (Day 8) and I again had 0 Ammonia, 0 Nitrites and 0 Nitrates. Could it have cycled? or is something else happening?
