The JBL ProTemp e is an external heater for aquariums. It is attached with a hose between the external filter and the filter outlet and thus heats the aquarium to the desired temperature.

Due to the possibility of shifting the temperature control of the tank so that it is located outside the aquarium, you can minimize the technology in the tank and nothing disturbs the perception of a carefully designed aquascape or nature aquarium.
