The Eheim Aquaball has 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 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.The ball shaped pumphead sits in a ball socket and can be turned right round, meaning the outflow of the filtered water can be aimed in any direction. The pump flowrate can be set by the control knob on the outflow nozzle. The power-diffusor can be adjusted to regulate the air intake and thus the oxygen enrichment in the aquarium.(Instead of the diffusor, other extension pieces can be used)There are 3 models for aquariums from 80 up to 240 litres.
