With permanent aeration of the pond, you’re never too late. The air bubbles keep the water moving, preventing it from freezing. In addition, harmful gases that have accumulated in the pond are removed. Choose a strong Silenta Outdoor Air Pump that can withstand the winter weather well. This air pump stands next to the pond and carries oxygen, via the air hose, to the air stone hanging in the pond. This prevents suffocation of the fish and keeps the aquatic biotope healthy.

Pond fish in winter

Has your pond frozen over anyway due to unexpectedly severe frost? Then never cut a hole in the ice, as the vibrations can cause internal injury to your fish. Make a hole by placing a pan of hot water on the ice. Then immediately install an ice freezer to keep the wak open.

Even when it stops freezing and the icing is over, the water temperature remains low. Pond fish are cold-blooded animals that take on the ambient temperature. Their movements and body functions are slower in cold water. So is their food intake. Feeding your fish twice a week is sufficient at water temperatures below 6°C. Give them special winter feed with reduced energy value. In addition, this food sinks to the bottom of the pond where the fish are.

Protection from herons

Hungry herons can also pose a threat to your fish in winter. The food supply is limited and pond fish are easy prey for the heron. Protecting your fish from this danger can be done in several ways. A fence with scare wire around the pond is very effective. When the wire is touched, an unpleasant shock is felt, causing herons, cormorants and cats to flee and stay away from the pond from now on. With the Ultra Protector A fence of 100 meters can be equipped with 2 electric fence wires.
