Eheim Professional 4+

Modern filters in different models
There are 3 models of the EHEIM external filter professionel 4+ for aquaria up to 250, 350 and 600 litres. The models 250 and 350 are also available with integrated heater as a thermo filter (T). The 350e model also offers electronic control from a PC (see professionel 3e).
But the highlight is the new "Xtender": If the filter masses are dirty and the water flow decreases, you can simply adjust the flow by turning the knob. This way you don't have to intervene immediately and gain a few days until the next cleaning of the filter media. The biological filtration (detoxification) is still maintained by diverted water flow.
The colour of the professionel 4+ has a new look. The filter is in modern anthracite grey and is supplied with matching hoses, tubes, etc.
