I live in zone 9b, and my water temp in the winter only gets into the low
50's. Is it necessary at that temp to turn my waterfall off? I have a
bottom drain where my external pump sucks the water from.
=================
I shut off the big pumps (I have 2 ponds) that run the show in summer. In
winter I leave a smaller 250 gph pump running in a corner of each pond to
keep an opening in the ice, if any. I'm in zone 7 but most winters here
are not that severe. They're too high and away from the deepest areas to
mix the water levels. The fish all just hang out at the deepest spot all
winter.
