Hey so far this site has been amazing with all the help I've gotten. I had been struggling with ammonia levels in my new tank. Now for the past two days my nitrites have shot up to 5ppm and my ammonia dropped to 0. Yesterday I did a 25% water change that only helped for a couple of hours. I added prime into the tank at midnight and seed to help. I think this is the second half of the cycle stage but not sure. I have live plants that have been getting brown spots all over them. No dieing leaves yet and I checked it's not algee. I use flourish root tabs and dose flourish liquid once a week. I've included a picture of my equipment and stock as well as a picture of one of my Anubis Nana. From the research I've done my tank is not overstocked. The only change is I had a guy from the aquarium tech store come out and set my tank up with CO2 this morning. I just check my nitrites and now there 0ppm. Is this normal or did prime alter my test? Should I expect another rise in nitrites? Any tips would be great.
