Winter Pond Care: Pump Management, Ice Safety, and Fountain Storage

Q: Two connected ponds (3 ft and 1 ft deep) with circulating pump. Run pump or shut off in cold weather?

A: Winter fish needs are minimal—they bottom-rest, stop eating, slow metabolism. They do need oxygen.

• Mild winters/no ice: Turn off pump, store it
• Occasional night freeze/thaw days: Little concern
• Extended freeze (days): Action required

Ice Management: Gently pry and crack ice edges—NEVER hammer solid ice. Water doesn't compress; fish do. Hammer blows = hitting fish directly. Better: install a pond heater to maintain open water. Running pump continuously helps but risks drainage if splashing freezes externally.

Q: Above-ground terra cotta fountain (5–7 gal). Screen for leaves? Winter rain? Antifreeze safe for pump?

A: In-ground fountains often run all winter. For above-ground: drain in November, store pump indoors until spring. Contact Atlanta Water Gardens for details.
