Nitrogen Cycle Question

Hi. We moved across country this summer and I had a 45 gal set up with freshwater fish that was going great. I’d done a fish less cycle and fish were healthy and thriving. When we moved I just dried all my gravel and decorations, filter media, etc. did not rinse in hope of keeping some form of good bacteria. Now I am trying to do my new fish less cycle in the new house, and things were moving along great! However, I am confused by how things are going. The ammonia dropped, and I saw nitrite show up. The last three days though, I have 0ppm of ammonia in less than 24 hours, 0.25 ppm of nitrite, and 5.0 ppm of nitrate. Did I miss the nitrite spiking? I started the cycle on a Friday and tested the first time the following Thursday expecting it’d take awhile, but ammonia was down to 1 ppm already.
So after redosing ammonia I decided to test nitrite and nitrate the next day... and they haven’t changed. Still 0.25 for nitrite and 5.0 nitrate. PH hasn’t dropped, it’s above 7.6. Any thoughts? Thanks.

I suppose you could have missed it. Did you actually dry out your filter media in this whole process? I'd be surprised if it dried out but came back for the cycle

Yes, everything had dried out since we moved in April and I’m just getting back to setting everything up now. Should it be taking this long for the nitrates to rise though?

How far along into this fishless cycle are you?
What are you using for an ammonia source?
What are you dosing to?
Have you tested your tap water for nitrites and nitrates?

Only about a week and a half. Dosing with Dr. Tim’s ammonium chloride up to 4 ppm. Have not tested plain tap water alone.

Ok, well there is no way a tank cycled in a week and a half. How old is your test kit? Are you using liquid reagents or paper test strips? Would also test the tap water for baseline measurements.

The API liquid test kit. It’s about a year and a half old.

possible that a little bit of the bacteria survived, it happened to one of our members a few months ago.

do a water change and keep dosing ammonia to 4ppm.

Even crazier results today-
Ammo- 0
Nitrite- >0, <0.25 ppm.
Nitrate- 5.0 ppm

nitrite definitely decreased.

If your dosing with ammonia? It looks like your BB did survive and your tank is cycling. I would think your in good shape.
