How do I keep my pond fish alive in the winter?
by
Place a pond aerator or a submersible pump on the second shelf of your pond so it bubbles right at the surface of the water. If winter temperatures aren’t drastically frigid, the bubbling of the pump should be enough to keep an open hole in the ice.
As long as your pond does not freeze to the bottom and an air hole is provided on the pond’s surface, your fish will survive the winter. If your pond is at least two-feet deep, the proximity of the earth to the pond’s surface will keep the pond from freezing any deeper than eight inches.
