Okay so I have a 10 gallon tank that has been running for a month now and I have 5 platys and 2 Panda Cory's in it. The ammonia level had been high since I set the tank up but about 2 days ago API Ammonia Test Kit I bought gave me a 0 ppm result. I also used the API 5 in 1 test strips and that tells me that my Nitrite and Nitrate levels are extreamly high. How is that possible? I thought that Nitrite and Nitrate are linked directly with Ammonia.
