When preparing your pond for winter, you have two primary options:
- Shut the pond down, or
- Keep it running through the winter
Each approach has its own requirements and benefits.
Option 1: Shut the pond down for winter (recommended in colder climates)
This is the most common and lowest-maintenance option.
- Turn off and unplug the pump, then remove it along with the check valve.
- Clean the pump thoroughly to remove scale and debris.
- The best way to clean the pump is by using Aquascape Pump Cleaner Maintenance Solution
- Store the pump in a frost-free location:
- Submerged in a bucket of water, or
- Stored dry on a shelf (follow manufacturer recommendations).
- Drain all plumbing lines, filters, and check valves:
- Water left in plumbing can freeze, expand, and crack components.
- Proper draining is critical to prevent damage and maintain warranty coverage.
- Remove and store external filtration systems (like pressurized filters) in a frost-free area after draining completely.
- Shut down seasonal equipment such as UV clarifiers or ionizers:
- These are not needed in winter and shutting them down helps extend their lifespan.
If you have fish:
- Keep a hole open in the ice for gas exchange:
- Use an aerator or small recirculating pump placed on a shelf (not at the bottom).
- In colder regions, add a floating de-icer:
- Thermostatically controlled to operate only near freezing.
- Keep aerator and de-icer near each other, but not stacked.
Option 2: Keep the pond running through winter
This option provides a beautiful winter appearance but requires more attention.
- Keep the pump and waterfall running continuously.
- Monitor for ice buildup:
- Prevent ice dams that can force water out of the pond.
- Regularly check and maintain water levels:
- Add water as needed due to evaporation and ice formation.
- Ensure consistent water flow to the pump to avoid damage.
Important considerations:
- Works best in moderate climates or with experienced maintenance.
- Requires routine inspection during freezing conditions.
- Ice formations can create unique and attractive winter features.
General winter tips (for either option)
- Remove excess leaves and debris before freezing temperatures arrive.
- Protect electrical connections from moisture and snow.
- Never break ice manually, as shockwaves can harm fish.
- Plan ahead for an easy spring startup by cleaning and properly storing equipment.
Choosing between shutting down or running your pond depends on your climate, maintenance preference, and desired winter appearance. In colder regions, shutting down is typically the safest and most reliable option, while running the system offers visual appeal with added responsibility.
