Tips On How to Keep a Pond Open in the Winter
Tip #1: Install a Good Pond De-Icer
The first thing you are going to do is to buy a quality pond de-icer.
The biggest worry pond owners have during the winter has to do with ice. If the water starts to freeze over, this can have a damaging impact on your fish and their ability to stay alive.
Yes, a lot of pond fish are resilient creatures and aren’t going to die quickly. However, anything that interrupts their environment will lead to health issues that aren’t something you want as a pond owner.
A good de-icer for your pond during the winter is a must.
The benefits include:
- Consistent Conditions for the Pond Fish
- Keeps the Water Moving
- Doesn’t Cause the Pond to Freeze Over
Once you set up the de-icer for your pond, it’s going to keep the water in good condition even as the temperature drops.
This is a must when you hope to make sure the pond remains open for as long as possible.
If you want to learn how ot keep a pond open in the winter, it’s best to start with something as simple as a de-icer.

Tip #2: Remove the Debris
The debris is a major concern when it comes to keeping your pond in good shape.
During the fall months, you are going to see debris all over the place. It’s natural, especially if you have large trees near the pond.
The leaves start to fall into the pond and leave quite a bit of mess behind.
As you learn how to keep a pond open in the winter, you have to focus on eliminating this debris right away.
The debris is going to be damaging and something no one wants to deal with when it comes to the pond and its overall health.
Plus, the debris is not good for your pond fish, which is another reason to quickly remove the leaves with a net or rake.
Tip #3: Stop the Pump
Is the pond pump still on?
It’s highly recommended to turn off the pump during the winter months. This will allow the fish to hibernate in peace and not have to worry about water movement.
Plus, your pond isn’t going to need the pump working when it’s colder outside.
Does this mean it’s a mandatory requirement?
Well, no you can always leave the pump running but it’s not something that’s ideal for specific types of fish including koi.
You want to let them hibernate and that isn’t going to happen when the water is moving all the time.

Tip #4: Create a Small Cover On Top of the Pond
This is different to a traditional tarp.
It’s never a good idea to take a tarp and just put it over top of the pond! This is going to ruin the fish’s cycle and that is not good for their health.
Plus, it’s not good for the water quality either! Sunlight is a part of keeping the pond in good working condition at all times of the year including the winter months.
As you learn how to keep a pond open in the winter, you have to focus on creating a small shed of sorts. This will let air come in through the side but isn’t going to let snow fall into the water.
Just create a small standing tent as that is all you are going to need.

Whether it is buying a good de-icer for your pond in the winter, removing the debris, and/or stopping the air pump, it’s recommended to go through all of these steps BEFORE the winter months.
