Velda Silenta Air

In many garden ponds, it is necessary to add an air generator to obtain a good biological environment, in which fish and plants thrive. Oxygen is released into the water in the form of bubbles. At the same time, the bubbles remove harmful gases from deeper in the water. That prevents the suffocation of micro life and fish.

When the water temperature rises in the summer, lack of oxygen often occurs. The fish will swim to the surface to gasp for air. And when you remove algae, you take away an important source of oxygen too. The solution is to aerate the pond. When in winter the pond freezes over, fish can often die as a result of suffocation, particularly in small shallow ponds. However, you should never chop a hole in the ice because the vibrations will harm your fish. Aeration of the water is a better solution. The air bubbles will keep the pond ice-free and the water oxygen-rich.

Simply plug in the air pump, attach the pump to the air stone with the fibre reinforced airline supplied with the pump! The Silenta Air Outdoor pump is rainproof and should be located next to the pond, we recommend covering this in winter or removing and bringing indoors.
