I have had a 20 gallon high for about 4 weeks now. There is 1 goldfish in it and a recently added Amazon Sword that is doing well. Diatoms started growing on it about a week ago. I have been testing the water about 4 or 5 times a week with the API master kit. My ammonia just started going down yesterday, my nitrite was absolutely 0, and my nitrate was slightly orange (maybe around 2 or 3 ppm). I tested the ammonia, nitrite, and nitrate today again today and there is practically no ammonia. Less that the .25 on the chart. The nitrite reads 0 (not even the slightest tint of purple) and the nitrate is about 5. From my frequent testing, I am pretty sure my tank never had nitrite yet the nitrate is climbing. Is this normal? As far as I can tell, this isn't how a tank should be cycling. Any thoughts???
