I guess the nitrates aren't coming down because of the limiting nutrient
here - CO2.  In my planted tank, I have to add some nitrates to maintain
a readable reading.

I think that you'll find adding CO2 is less work than worrying about
nitrates and doing water changes twice a week to keep them down.

Another point folks often make is that aquariums do not run themselves -
some kind of management is needed to keep things healthy.

So, I guess you can choose nitrate management if you want to.  It's a
legitimate aspect of aquarium management.  But, growing bigger plants is
more fun.  :-)

The reason you have high nitrates is not because of the biowheel.  In
fact, it's doing it's job well if all you see are nitrates (No ammonia
or nitrItes).
