Small update.

The last few days I have seen varying ammonia levels that I would call "non-zero" to as far as maybe 0.125 ppm, only as it appears to be halfway between the yellow zero and the 0.25 yellow green. If It don't quite look like yellow zero I just call it >0. This morning it was definitely unquestionably zero and stayed there for 10 minutes in the test.... Sometimes if I leave it longer than the recommended 5 minutes it continues to shift a bit more, this did not.

I expect to see a little nitites soon.

Jeff.

Added fish on Saturday afternoon. Saw ammonia levels increased to 0.25 late Sunday morning then dropped to near zero early Sunday evening.... approximately 5 hours later.

This morning the ammonia and nitrites are zero.

I am not surprised by the quick ammonia correction, I am comfortable with letting low levels of ammonia look after themselves as I have a lot of plants. My only issue from the first of this thread was that I had no idea what to expect with the unknown factor of the nitrospira bacterial capacity to consume high levels of nitrites... particularly when the test (however accidentally high it may have been) was in the 4ppm range. Had it been 1 or under, I might have just monitored it.

I can see why you think I wanted to know about water changes.

actually I was only interested in the time it took with plants to consume the ammonia.

You may or may not see nitrItes. But if you are not feeding or otherwise adding bioload (even the ammonia), then nitrItes could have only a very low 1 day type spike or none measureable at all.

You could notice a jump in nitrAtes though.

Still Just my .02

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Yes, that is more or less what I am watching for.

I have a theory about cycling that runs counter to the crowd mentality... it looks good on paper and it certainly matches what I have seen in my tank so far.... hopefully it's not as controversial as water changing though.
