Maintain a stable and comfortable aquarium temperature with the Fluval T-Series Fully Electronic Aquarium Heater.

Fluval T-Series heaters combine accurate electronic temperature regulation with continuous monitoring and multiple built-in safety features. The adjustable thermostat allows you to select a temperature between 72°F and 90°F, while advanced sensors monitor the aquarium around the clock to help prevent large and potentially harmful temperature fluctuations.

A highly visible 360-degree indicator ring makes heater operation easy to check from nearly any angle. The ring illuminates red while the heater is actively heating and changes to blue once the selected water temperature has been reached.

For additional protection, the T-Series automatically shuts off when removed from the water, helping prevent overheating and accidental damage. An integrated heater guard provides another layer of protection against breakage and contact with aquarium inhabitants.

The fully submersible design may be installed vertically or horizontally, allowing flexible placement inside the aquarium.

Choosing the Correct Heater

Select the heater according to your aquarium size, room temperature, water volume, and desired aquarium temperature. Colder rooms or aquariums with significant temperature differences may require additional heating capacity.

Installation and Safety

Position the heater in an area with consistent water circulation to distribute heat evenly throughout the aquarium. Ensure the heater remains fully submerged during operation.

Always unplug the heater before performing water changes, removing it from the aquarium, or exposing it to air. Allow the heater to cool before handling.
