Yes, it is getting close, but it can still take a few days before you will get a 0ppm reading on both ammonia and nitrite during your night test. Do not forget to do the partial water change before dosing ammonia again. The nitrate buildup is enormous and quick. I would also like to recommend you to do the night test before the water change instead of after. You will know the exactly reading after the water change if you know exactly percentage water you have changed. The reason is being that at very low concentration, the reading might not be as accurate at higher concentration (but not too high, which will also become hard to read).
