I am on day 14 of my cycle. It's a 55 gallon tank. It came with two packets of dechlorinator with bio spira in it so I used that, I kind of wish I hadn't now. After getting the tank set up I dosed it up to 4 ppm using the Ace Ammonia and after a few days it went down to 1 I'd say after about 5 days. I dosed it again up to 4 ppm and it just stays there. I had been sprinkling in finely crushed food since the beginning. I have done one 40 to 50% water change, raised the ammonia back to 4 ppm and added more food since then. Now on day 14 I'm a little baffled that the ammonia has stopped after watching it go down once. I'm wondering if the bio spira had caused that. I have not detected any nitrites at all. The PH is around 8. I'm using the Freshwater API master kit. Should I do another pwc and add more crushed flakes or just be patient and wait it out? I have no problem with being patient, I'm just confused with why I saw an ammonia drop and now I'm not seeing anything.
