I'm doing a fishless cycle on a 10 gallon tank with an AquaClear 20 filter without the carbon in it. Thursday night, I took my readings, and they were ammonia at .25(dosed back up to 4), nitrite 2.0, and nitrate 40. I also threw in some flake fish food that I pulverized to a powder to keep some ammonia going over the weekend. Just got home tonight, and my ammonia is 0, nitrite is 0, and somehow my nitrate is down to 0. The pH is 8.0 and the temp is 76F. I did the nitrate test twice thinking I somehow made a mistake, and it cam out the same both time. There are no signs of algae, and no live plants in the tank.
What happened to the nitrates? I thought that without plants the only way to remove them is to do a PWC.
Thanks in advance.
