With EHEIM biopower you have a high performance internal filter that has never before existed.

It has got its all-round rotatable pumphead, its modular construction and further features from the aquaball concept.

The special thing about biopower is that it offers multi-layer filtration just like an external filter. The closed filter baskets are filled with highly efficient filter medial (e.g. SUBSTRATpro). The inlet basket with filter cartridge for the mechanical-biological prefiltration is located at the bottom. The water sucked in at the bottom is pumped to the top through the various filter layers and after filtration directed back into the tank.

There are 3 models for aquariums from 80 up to 240 litres.

Benefits of the Eheim BioPower Internal Power Filter:

Multi-layer filtration just like an external filter
Modular construction with closed filter baskets, filled with EHEIM SUBSTRATpro; inlet basket with filter cartridge (Other filter media can also be used)
Pumphead holder at the top with filter pad and cover grill
All-round adjustable pumphead to direct the outflow as required
Fitted with power-diffusor for strong oxygen enrichment and a wide jet nozzle for natural surface water movement
Easy removal and repositioning of filter baskets with Easy-Klick locking system
Suitable for aquariums with light to moderate stocking (Fish 5 cm); for fresh or marine water
Complete with original EHEIM Filter media and ready for use

Directly under the pumphead is a mediabox. It can be filled with:

a filter pad for mechanical-biological filtration,
a fine filter pad for fine filtration/polishing,
bioMECH or SUBSTRATpro for biological filtration or
EHEIM AKTIV for adsorptive filtration.

Also biological as well as adsorbtive filter cartridges or filter pads can be placed in the other filter modules.

Aquaball has a modular construction. This means that by adding or removing filter modules (filter baskets) you can adjust the filter volume as necessary.

For extending the filter use ExtensionSET2
The filter baskets can be easily clipped together and released (Easy-Klick Locking System)
Due to the modular construction the filter cartridges or media can be cleaned at different intervals thus preserving bacteria cultures.

Aquaball sucks in water over a large surface area. The round filter modules are designed so that the water is absorbed evenly from all sides over almost the whole surface area.

The holder for aquaball is simply fixed to the glass with suction cups. For cleaning, exchanging modules or filling with filter media, the filter is simply removed from its holder.
