I've seen solar powered water pumps/fountains
before but today's catalog has a solar powered
air pump to 'encouraging consistently clear
and clean water'. It is $59.50. The catalog
is SolutionsCatalog.com I guess it would be
dollars to donuts, a solar powered fountain
or air pump for the health of the pond, don't
you think? Both lack running at night time
when plants switch from producing O2 to
consuming it.

I run an air pump in my deck pond, plugged
into the wall socket. Last year the deck pond
held a tropical lily. This year jan's lotus is
in there. The air pump has been taken out of the
pond and will be moved up to the deck soon.

Run an 110v airpump pump on a timer, from sunset to sunrise, use the solar
powered one to circulate water at the far end of the pond, away from the
waterfall. Or use it as a freebe to improve circulate in the biofilter.
Having said that, my favorite line on that website is "Maintaining a balance
of oxygen in your pond can be tricky: there must be enough for fish and
microbes, but not too much to cause algae to thrive and take over."

Good thing nobody uses ozone to sterilize[1].
