Product Information

The Eheim 2171 Professionel 3 250T External Thermo Filter is for aquariums up to 250 Litres, with its unique motor system it simultaneously cleans, circulates and maintains temperature precisely - in one device.

With an Eheim thermofilter you can forget about the need for a separate heater in the aquarium - an ingenious innovation: the water is sucked in, filtered, at the same time heated and flows back into the aquarium at the correct temperature.
