Who this list is for
This checklist is for backyard pond owners who need to get their fish and pond ready for winter. If you keep koi, goldfish, or other outdoor pond fish, and your area has cold winters, this list will help you cover the basics. It’s especially useful for those who want to avoid last-minute scrambles or missed steps as temperatures drop.
How to use this list
Start by walking around your pond and checking what you already have on hand. Use your pond thermometer to monitor water temperature, and your water test kit to check water quality before cold weather sets in. Remove leaves and debris with a leaf net and pond skimmer net. Use the pond vacuum for deeper cleaning. If you use a pond-safe bacteria product, add it as directed. Dechlorinator is needed if you top off water. Switch to cold-water fish food and use a floating feeding ring to prevent excess waste. When the temperature gets close to freezing, install your pond heater or de-icer and set up the aeration pump, airline tubing, and air stones. Make sure your weatherproof outlet cover is secure for any outdoor electricals.
Common mistakes
A common mistake is waiting too long to start, which can stress fish and make cleaning harder. Don’t skip the water test kit—water quality matters even in winter. Avoid overfeeding once water cools; fish metabolism slows and uneaten food can foul the pond. Some skip the aeration pump or de-icer, risking fish loss if the pond surface freezes solid. Don’t forget to check your weatherproof outlet cover before plugging in anything new.
What is on this list
You’ll find items like a pond thermometer, water test kit, leaf net, pond skimmer net, pond vacuum, dechlorinator, pond-safe bacteria product, cold-water fish food, floating feeding ring, pond heater or de-icer, aeration pump, airline tubing, air stones, and a weatherproof outlet cover. Cross off what you already own and check the condition of each item before cold weather arrives.
Before you go
Before winter truly sets in, double-check that all equipment is working. Store summer gear you won’t use. Test your de-icer or aeration pump for a few hours. Confirm you have enough cold-water fish food to last the season. Once everything is set, monitor the pond regularly for ice coverage and water quality. If you need help, contact a local pond specialist.
