The EHEIM professionel 3e is the first electronically controlled aquarium filtration system. Its design features a compact, user-friendly control panel offering many advantages in the field of aquaristics. An output control regulates all operational settings electronically, and the maximum output of the filter is far superior to that of comparable models. A so-called stream function electronically creates and controls an alternating water flow, thus creating near-natural conditions in the aquarium. In addition, the filter includes an integrated safety hose adapter with shut-off tap and a new automatic priming aid for easy filter start at the push of a button. The 2076 has 3 media baskets and holds 3.3 gallons of media. Filters 435 gph and is rated for tanks up to 105 gallons.
