Hey everyone, I just set up my new tank about a week ago and so far everything is going pretty good. Three days after I set the tank up I tested my levels and I had ammonia at 0 nitrite at 0 and nitrate 20-40 (I really couldn't tell the difference in the color on the card) Today I tested and basically got the same numbers except this time the nitrates might have been more on the closer side to 40 but still in between 20-40. The rock I used was live rock from my LFS. They had it curing in a tank for who knows how long. It could have been a year, but it was sitting in there for at least two months. So what I'm wondering is if I skipped the ammonia and nitrite spike because of the condition of the rock. Thank you!!
