Not if you want fish or the possibility of night viewing. Fish need oxygen,
and they need it the most at night when plants reverse themselves and start
consuming oxygen instead of making it. If you shut off the pump, you'd
better plan on putting in an air pump instead.

And shoot, at night - a pond without movement is just a big puddle G!

Has anyone ever used solar pumps for the pond or a fountain? I'm
wondering if this would be a viable option when I finally get up the
gumption to begin digging!
