EHEIM Surface Skimmer The surface skimmer provides a permanently clean water surface, reducing oily film residue and therefore contributing to a reduction of microorganisms, better oxygen exchange and greater light penetration. It skims off the film residue and constantly brings new layers of water to the surface. Further information: The film residue is an unsightly film on the water surface of the aquarium Organic material like fats, proteins and waste matter gather here, forming a feeding ground for a host of unwanted microorganisms. The surface is, however, necessary for the essential oxygen exchange between the water and air. A film on the water surface reduces both the rate of diffusion and, on the other hand, the on-going biological surface processes also needed for extra oxygen. Light penetration will also be reduced and consequently plant growth as well as photosynthesis will be compromised. Ensures a clear water surface, skims off oily film residue Reduces level of microorganisms on the water surface and contributes to a better oxygen exchange and more light penetration Constantly brings new layers of water to the surface Floating surface intake mechanism (ca. 2 cm), adjusts to the level of the water Automatic valve control at the bottom inlet, e.g. in case the surface intake becomes blocked Consistant water intake, guarantees no air intake Shut off of surface outlet e.g. for feeding Telescopic design for all sizes of aquarium Attachable to all external filters in place of the intake pipe; For larger EHEIM Filter a T-reduction piece is necessary for connection
