help Fluval E Series Submersible Heater FAQ
Which Fluval E Series heater size fits my aquarium?
Fluval rates the E100 for up to 30 US gallons, the E200 for up to 65 gallons, and the E300 for up to 100 gallons. A cold room or unusually tall tank may require more heating capacity than volume alone suggests.
What do the changing colors on the Fluval E heater display mean?
The VueTech display changes color to show whether the water is near the selected temperature or outside the expected range. This makes an over-temperature or under-temperature condition visible without reading a separate thermometer.
Why is my Fluval E heater showing a low-flow warning?
The heater needs moving water to distribute heat and measure the aquarium accurately. Position it near the filter outlet, while keeping the flow appropriate for the fish and plants.
Does the Fluval E Series need a separate heater guard?
No. The E Series has an integrated protective casing that keeps fish and aquarium decor away from the heating core.
