Got a odd problem going on with my tank. I was in the middle of the cycle and ammonia was 0 and the nitrite was 5.0ppm+ and was doing daily water changes which help bring it down some. Some members told me about prime, so I went out and bought some and been using it when I do water changes and by the directions. Question is I tested everything last night and haven't done any water changes in the past few days and my test come back. 0 ammonia, 0 nitrite, and 0 nitrate. Could it be the API kit giving me false readings or the prime. I am not sure if my tank flipped on me or what.
