The residue film – the unsightly surface film on the water surface of every aquarium – is the place where organic substances such as fats, proteins and decomposition products deposit which form the breeding ground for a large number of undesirable microorganisms. The surface is however also decisively important for the vital exchange of oxygen between water and air. On the one hand, a film on the water surface reduces the diffusion rate; on the other hand the biological processes taking place there consume additional oxygen. In addition the entry of light through the surface of the water is impaired, which is disadvantageous for good plant growth.
The EHEIM surface skimmer provides for a clear water surface by removing the residue film continuously and bringing new water layers to the surface.
Its decisive advantages:
- Prevents surface film.
Prevents undesirable biological processes on the water surface.
Hence optimum exchange of oxygen.
Therefore light enters unimpeded for better plant growth.
- Mobile inlet float with a level compensation of approx. 2 cm, which adapts to the height of the water surface.
- Automatic valve control of the lower priming area, for example when the inlet float is plugged.
- Constant water inlet, reliably without suction of air
- Surface removal stop function, e.g. for feeding.
- Telescopic design for universal aquarium sizes.
- Suitable for suction filters up to 1500 L.
The skimmer can be connected to any external canister filter instead of the priming pipe. A T-reducer is necessary as a connection piece for larger EHEIM filters.
