I really think you should look into a low-wattage pump, rather than turning
yours off daily. Maybe just one for the filter, and one you can turn on and
off for the waterfall.

I guess I could try it and test the water very closely to see if it
degraded the bacteria in the bio filter. I was just hoping to see if
anyone had tried this before. Thank you for the feedback -- much
appreciated.
