Ensure the health of your fish during the season!Oxygen-rich water is essential for a healthy pond environment and healthy fish. To keep the pond ice-free in winter and well aerated in summer, an effective solution is a Discus float with an air flow underneath. The air bubbles ensure a continuous flow of water along the float, keeping the surface open even in frosty conditions.Winter: Freezing of the garden pond can often lead to the death of fish, especially in small and shallow ponds there is a risk of suffocation after freezing. Aeration not only provides oxygen, but also prevents the pond from freezing completely.Summer: As the water temperature rises, there may be a lack of oxygen. If the fish come to the surface to gasp for air, this already indicates a lack of oxygen in the water. Water aeration then comes to the rescue.This set contains a pump, a Discus float, 10 meters of air hose, an air stone and a replacement membrane.
