See? Now wait until you hit zero ammo again and then redose ammo. Keep doing it until you hit 0 ammo and 0 nitrites. Then, dose one more time, if you hit zero for both again you are cycled. Your nitrates should be off the chart. Do a large water change to get your nitrates below 20ppm. If you won't be adding fish right away dose ammo to keep your BB fed. Just make sure that when you do get your stock, to make sure your nitrates are below 20ppm.
