I started my fishless cycle about 3-4 weeks ago. I used dr. Tim’s ammonia to dose and used either Stability or Nite-Out every other day. I also added medium from another established tank and live plants. I’ve kept my water to around 78 degrees. About two weeks ago my nitrites reached about 5 ppm and my nitrates where around 100pm. I did some water changes to bring it down and kept an eye on it. Nothing changed much. Today I did 2 large water changes. When I tested with the API test kit I got ph: 7.0 ammonia: .25ppm nitrites: .25ppm and nitrates:20 ppm I don’t understand why nitrates seem to be going down and ammonia and nitrites are still there. Also, my LFS suggested I come back tomorrow and get some feeder fish. I’ve come this far without torturing fish, should get some like they suggested?
