Update: Tank is cycling well so far. Ammonia is going down, and nitrite is starting to spike. There is also some nitrate appearing in the tank. I am also cycling a smaller 5.5 gallon tank at the same time that I plan to use for a hospital/quarantine tank. Both are in the living room, the 10 gallon on the entertainment center, (Tank 1) and the other on the hutch (Tank 2) Tests today show ammonia at .50 ppm, nitrite at 4 ppm and nitrate at 5 to 10 ppm for both tanks. Fishless cycling with ammonia works and is much more humane than cycling with live fish. I can hardly wait until the cycle is complete in both tanks and can add my new fish!
