Eheim 300W Sizing and Placement Notes
The Eheim 300 Watt Thermocontrol Aquarium Heater is intended for larger aquariums with higher heating requirements. For very large systems, long aquariums, or sumps with multiple compartments, using more than one heater may provide better temperature balance and redundancy.

Mount the heater fully submerged in an area with strong, consistent water movement. Set the desired temperature on the dial and allow the aquarium to stabilize before fine tuning. Disconnect power before removing the heater from water or performing maintenance around it.
