Eheim - biopower 240 internal filter

External filter technology and multi-layer filtration – that means: the water at the bottom is pumped to the top through the various filter layers and after filtration directed back into the tank.

 

The closed filter baskets come prefilled with EHEIM SUBSTRATpro. Other filter media can also be used. 

The inlet basket contains a filter cartridge for the mechanical-biological  prefiltration. In the pumphead holder a filter pad provides additional filtration. 

 

By adding or removing filter modules (filter baskets) you can adjust the filter volume as necessary. 

The ball shaped pumphead sits in a ball socket and can be turned right round. Thus the outflow of the filtered water can be aimed in any direction. 

 

The pump output and throughflow can be set by the control knob  on the outflow nozzle. 

 

The  power-diffusor is adjusted to regulate the air intake and thus the oxygen enrichment in the aquarium. 

(Instead of the diffusor, other extension pieces can be used; see accessories)

 

The holder for biopower 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.
