I am currently on day 27 of my fishless cycle. I started with marco rock and non live sand for a 2 in sand bed. I used Brightwell Start XLM and added ammonia to around 1.2 ppm per the Red Sea test kit. My question is that after 27 days my ammonia level has not changed but my nitrite level has steadily increased. I'm in no hurry to get through the cycle, but i'm confused as to why the ammonia level has not changed if its being converted to nitrite.
