Ok thanks for the reply. My tank has been up for 21 days. I used fritz turbo start to cycle the tank. My nitrites and ammonia were at 0 after two weeks. Initial reading were 5 ppm for both ammonium and nitrite. I added ammonium hydroxide to cycle the tank. In the 2nd week my nitrates spiked to over 50 ppm. Over the course of two days I did multiple water changes. I was able to lower my nitrates to 17.6. During the nitrate spike I removed the bio balls in order to use algone nitrate remover. Removing the bio balls probably caused my issue(I thought I had enough bio filter with live sand and live rock to cover the removal). I still was getting 0 readings on ammonium and nitrite so I assumed my tank was cycled. I went out and got midas blenny. After two initial feedings my nitrite spiked to 2 ppm. Remarkably my midas blenny has not perished. I checked the readings this morning. My nitrite was reading .50 ppm. If my reading is still the same tomorrow, I am going to add Seachem and do a water change. My Blenny is still ok. He has only been in my aquarium for two days. He did eat a little bit yesterday before the spike. He hangs out in his cave. I didnt realize Blennies were that hardy of a fish. I assumed he would have died after the spike.
