I think it’s cycled. Need 2nd opinion

First photo is of today. There’s a trace amount of nitrites but ammonia seems to be at 0 or very close to. The 2nd photo is about 4 days ago. As you can see, ammonia and nitrites are clearly detected.
Do you think my tank (fish-in) is in the last leg of cycling?

Well my test kit always says there's ammonia regardless if it's even tap, so that could be the ammonia. Your nitrogen cycle probably isn't complete if there is nitrites, there's probably just not enough bacteria built up, I'd give it a few more days, test now, and once each day for the next couple days.

When you have 0 ammonia and 0 nitrites with a nitrate reading you've completed your cycle. If you have like 0.25 ppm ammonia, 0 nitrites, and 20 nitrates, odds are you've completed your cycle but it is too weak to sustain fish yet. When I see that happen I simply redose and let it run for a few days. If I get 0 ammonia and 0 nitrites after then I know my cycle is 100% finished.

You are presently in the nitrite stage. You are showing some ammonia, but you are also showing nitrites. The ammonia simply hasn't been fully processed yet. I bet if you test tomorrow you'll see 0 ammonia with some kind of high nitrite reading.

Post back if your tank stalls out on the nitrite stage. This happens to me once in awhile. I usually just use a bottled bacteria product or transfer a tiny amount of cycled media in to help. For now you have no reason to worry. I'd say that everything looks the way it should

-----------------------------------------------------------------------

ALSO, this info is meant for the first time you run a cycle. If you use the right media then eventually your bacteria colony will start to diversify and process nitrates as well. When I run cycles I see 0 ammonia, 0 nitrite, and maybe 10 nitrates for about 1 week, then I see 0,0,0 from that point forward. If you want to learn more please feel free to DM me. There are a lot of myths about nitrates and cycling in general in this hobby... myth #1 is that you NEED to see nitrates or else you "aren't cycled." This is more advanced stuff though and most people just allow nitrates to build up so don't let this confuse you.

Thanks! I’ve been dosing daily with Stability. I have an Aqueon QF 10 that I modified with media instead of cartridges.
Everything in my tank, real and fake plants and decorations are getting a brown “algae” build up on them.

Sounds perfect. Let us know if you have any other questions :)

Here’s today’s results 5/08. I think I’ve finally hit the final leg. Now what?
