Whether for breeder or quarantine tanks or simply for typically smaller "home" aquariums: internal filters are ideal. They take up little room and are extremely flexible. For these purposes EHEIM offers various options for aquariums from 45 up to 260 litres: all of them (apart from pickup) are modular, can be extended or reduced to suit all requirements.

EHEIM aquaball the variable modular system with a spherical head. The outflow direction can be adjusted as required, the filter volume can be customised, different filter media can be used and it has much more besides.

With Aquaball, Eheim offer you an award-winning* internal filter concept with all-round benefits

The ball is the trick. The round pump head sits in a ball joint. This enables adjustment of the outflow direction as required. The flow rate is set by the output regulator. And the power-diffusor adjusts the air flow.

Due to its modular system the filter volume can be customised as required. The filter baskets are easy to clip in and remove and can be filled with a variety of filter media.

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.
