The Oase Pontec PondoPolar Air Preventer is a simple but highly effective solution to the problem of ponds icing over. An Iced over pond is a danger as it will prevent the natural exchange of oxygen at a pond's surface and trap harmful toxic gases within your pond - gases which can harm or even kill your fish.
Made of polystyrene the PondoPolar is a float device which will stop a small area of your pond surface from freezing over. Effective down to temperatures of -15°C, the vent slots will allow harmful gases out and fresh oxygen in. As well as the vent slots the ingenious design also incorporates a ballast chamber that can be used to weigh the device down using sand to create a semi-submerged placement, or to stop it from blowing away in high winds.
The PondoPolar Air also has an air pump attached to the main device. The supplied 100 l/h air pump is fully suitable for outdoor use with an IP44 protection rating and will provide extra aeration and movement of the pond water, generating additional amounts of clean oxygen.
