How do you make a garden pond winter proof and how do my fish survive the winter? Just take note of our 3 golden rules!
If you enjoy a pond in your garden, you often wonder what happens to my fish when the pond is frozen over. Will my fish still get enough oxygen?
Small ponds need a total cover of transparent material, so that snow does not restrict the lighting conditions under water. On two sides, the pond must remain open so that oxygen can penetrate below the ice surface. These pages must not be cold, which means you have to keep tapping them if necessary.
But before you winterize your garden pond, there are a few more rules to follow.
Rule 1 – Clean the water
Old plant stems and dead plant parts, as well as fallen leaves are to be removed in principle. Otherwise, fouling gases are created in the water, which can “tip over” the biological balance. Also leaves and mud at the bottom of the pond must be removed.
Rule 2 – Add fresh water
Next, a part of the water must be replaced with fresh, because only clean water, the fish healthy survive the winter.
Rule 3 – Leave fish alone
Too much ice breaking disturbs the peace of the fish, so it will do more if you just break up a bigger hole.
