Firstly, what does a pond pump do?
Your pond pump is essential to your pond set-up, especially if you keep pond fish. It is responsible for circulating and moving water within your pond, providing essential functions like oxygenation, aeration, and filtration. With this in mind, the more populated your pond is, the more important a pond pump is.

Should you leave a pond pump on all the time?
You should run your pond pump 24 hours a day to ensure a healthy environment for pond fish. This will ensure your pond water is circulated and pushed through the filter, keeping your pond water clean while ensuring a habitable environment for aquatic life.
However, pond fish behaviour changes as winter rolls around, with some fish species even going into hibernation. This poses the question, do you need to keep your pond pump running in winter? Learn more below.
Should I keep my pond pump running in winter? What to consider
Whether you should keep your pond pump running in the winter depends on various factors, including the temperature, the type of pond pump you have, and the specific needs of your pond and its inhabitants.
Your pond inhabitants
Providing sufficient oxygen during winter is crucial for the survival of pond fish. This is especially important if your pond is prone to freezing, which can lead to depleted oxygen levels and fish fatality.
With this in mind, if you have fish in your pond, you should keep your pump running during winter. This will prevent the water from freezing and ensure fish have enough oxygen to survive.
The temperature
If you live in an area where the temperature consistently drops below freezing, running your pond pump during winter can damage your pond equipment. To avoid this, you should remove your pond pump and drain and clean it, storing it somewhere appropriate in preparation for the arrival of spring.
However, if you have pond fish, running your pond pump is crucial for their survival, performing essential functions like aeration and circulation. With this in mind, to avoid damaging your pond equipment during winter while ensuring a healthy environment for fish, you should decrease your pump’s flow rate and move it away from the bottom of your pond.
Your pond depth
Deeper ponds are less likely to freeze during winter, allowing enough oxygen for fish and other pond inhabitants. However, shallow ponds are more susceptible to temperature changes, which can be stressful for fish. If your pond is shallow, you may need to consider extra measures to prevent freezing and allow toxic gases to escape, including running your pond pump and buying a pond heater.
Fish health
Different fish species have different needs and tolerances to the cold. While some fish become dormant and require less food and oxygen during winter, others require more care. So, researching your specific fish species is crucial to their survival during winter.
The benefits of using a pond pump during winter
Running your pond pump during winter is crucial for fish survival. Here are four of the main reasons why:
Oxygenation
Maintaining sufficient oxygen levels is crucial for fish, especially during winter. Running your pond pump during winter prevents oxygen depletion, which can be fatal to fish and other pond inhabitants.
Water circulation
Pond pumps help circulate your pond water, which prevents it from stagnating. This is essential to prevent a build-up of debris and other matter, which can encourage algae growth if left stagnant.
Preventing freezing
By promoting water circulation, pond pumps help prevent your pond surface from freezing during winter. This is especially important as it allows oxygen to enter, sunlight to penetrate, and harmful gases to be released, keeping the water safe for your fish.
Preventing ice damage
In extremely cold areas, ice can apply pressure on the sides of the pond, potentially causing damage. However, keeping the water in motion can reduce this risk and ensure the integrity of your pond’s structure during winter.
Spreading beneficial bacteria
Some beneficial bacteria in the pond continue to function at lower temperatures, so running the pump can help distribute these bacteria throughout the pond, aiding in the decomposition of organic matter and maintaining water quality.Ω
When don’t you need to run a pond pump during winter?
If you don’t have pond fish or aquatic life in your pond, there is no reason to keep your pump running. The only reason to keep your pond pump running is to ensure the survival of aquatic life or for aesthetic purposes if you want to continue running water features like a fountain.
Should you leave a pond pump on all the time for fish?
Your pond filter is a life support system for your fish, ensuring the pond water is consistently clean, healthy and inhabitable.
Fish require oxygen to survive, and stagnant water can have high ammonia levels, which can be toxic. With this in mind, keeping your pond pump running all the time is crucial for fish health and well-being.
