Nitrates at high levels are not harmless to fish, it will kill them
eventually!


I didn't say they were harmless at high levels. They are harmless as long
as they don't get extreme. That is why I qualified my statement by
saying.

"As long as you are doing your weekly water changes, don't
worry about it."

I'm inclined to agree with this. Apparently I'm a more casual hobbyist than
ya'll. I have never monitored my water for anything, and my fish always seem
to live forever. I do change the water and clean the gravel pretty
regularly, and the rest seems to take care of itself. Algae is my biggest
battle, but it's certainly not overwhelming. The fish don't seem to mind it
