The Eheim Surface Suction Extractor prevents surface film. It also prevents
undesirable biological processes on the water surface, by providing an optimum
exchange of oxygen. This processes allows light to enter the aquarium unimpeded
for better plant growth.
The extractor takes water through the strainer at the top and has a floating
surface intake as well to help remove surface debris. The skimmer also features
an automatic valve control mechanism and a surface outlet block circuit so the
skimmer can be shut off for feeding.
The skimmer hooks up to the intake of the Eheim 2211, 2213, 2215, and 2217
filters. The T Reducer is needed when using the extractor with the 2217 filter.
The Eheim Surface Suction Extractor is for suction filters up to 400gph. It is
green to blend in with any natural setting.
The direction of flow must be towards the skimmer with the spray bar at the
opposite side of the aquarium from the skimmer.
