Fishless cycling?

If you only add ammonia once a day, you might as well bring it back to 2.0ppm.
It is obviously at this stage, your tank will run out of ammonia before it run out of nitrite. Nitrite reading will also be affected if ammonia is at zero for a while since nitrite is from ammonia.

We all must be patient during fishless cycling. Your jump start is very successful. Many of us had to cycle our aquarium for up to two months in the old days. Today, all these live bacteria products make fishless cycling so much faster than it used to be.
