I took a test today, day 10, and I have 4ppm ammonia and 2ppm nitrites. The ammonia has been the same for the last few days. I added like a little more than a tablespoon on sunday(3 tablespoons is 1ppm for my tank) and haven't added any sinse. The last time before that was on Friday, when I added 3 tablespoons. My nitrites yesterday were about .50ppm. When do you think the cycle will be over?
