I have an Aqueon 14g FW tank that has been cycling for 7 weeks using pure ammonia. About a week ago, I had the ammonia returning to 0 within 12-18 hours, Nitrites sky high and Nitrates at 5-10ppm. Then I added about 1/2 gallon of declorinated water to account for evaporation. I also added a large amount of decorations (plants, artificial coral, etc) to finish decorating and prepare for my fish. The problem is that since then, my cycle has stalled. The ammonia levels increased to about 3.0 ppm, probably because of the ammonium in the water I added. Now the ammonia is down to between 1-2 ppm and has stayed there for the past week. I have not added any additional ammonia. The nitrites are still sky high and the nitrates are still 5-10ppm. Did I stall my cycle by adding the decorations? I have raised the temp to 82 degrees but that hasn't helped. I have had an air pump in the tank since about the second week of cycling. Does anyone have any thoughts about what's wrong? Or is this just a matter of having patience? Thanks in advance for any thoughts!!
