So, I have been cycling my tank for around 4 weeks now and have been using the API master kit to test every day or two. Until yesterday I had 0.25 ammonia, 0 nitrites and 0 nitrates. I tested it today and it was 0.25 ammonia, 0 nitrites and 5 nitrates. I want to know why I still have ammonia if it has reached the last stage of cycling? Also, how has it completely skipped the nitrites stage of the cycle?
