With the Eheim thermopreset heaters, getting your aquarium up to temperature could not be easier. These are 'pre-set' to 25c which is the ideal for the most common aquarium inhabitants. The compact design makes them perfect for small tanks, and the built-in heater guard protects fish such as Pleco's which like to rest on heaters.
