I'd think it possible to be less "all- inclusive" in the definition of
stability, but we can look at things in this light well enough, too.

This part of "stability" would imply its duration...

The comparison here was not to define "natural" - just to show that even
Nature must re-do things on an interval. This goes back to the point of

And point number 3 leads to aesthetics - after all, you observe that plant
growth and tank health aren't affected. But the presence of anaerobic
activity still troubles you...
At this time, I'd say a comparison of techniques is in order. You're doing
something very different than I am with the same materials and we're getting
divergent results. In my view, sand *is* a viable, long- term substrate
requiring very little intervention on my part - only the occassional
addition of substrate fertilizer. But in order to determine where our
divergence occurs, some more information is necessary.
In the meantime, I found another example of long- term sand use:
