It's a 20 Gallon high. 1 Gourami, 3 Cory Cats, and 2 Red Fin Tetras so far. It's a month old and non-planted. I used a variety of products to get the cycle started with no results. I found out about Bio spira and added it to my tank 4 days ago, after doing a ton of water changes to bring down the Ammonia to a very slight level so the Bio Spira had a fighting chance and wasn't killed off by too much ammonia. On the 2nd day I finally had Nitrite of .25 and Nitrate of 5.0., it's working, yay. But my ammonia went back up to 1.0. I just did another test and my ammonia is up to 2.0, Nitrate is 10, and Nitrite is still .25. How is the bacteria making NO2 and NO3 without bringing down the ammonia? I want to do a water change to bring it back down but I don't want to lose any of the Bio Spira that hasn't attached itself to anything yet. Everything I've read on Cycling says that my ammonia should be 0 at this point or at least going down, I'm just really confused. This is my first tank.
