Fluval M50 Ultra-Slim Submersible Aquarium Heater - 50W Underwater Heater for up to 15 Gal Aquariums

The Fluval M Submersible Aquarium Heater boasts a European manufacturing quality that utilizes superior components and construction. This sleek, compact heater is ideal for use in freshwater and marine aquariums up to 15 gallons, with a temperature range of 66-86 degrees Fahrenheit. Unique to the Fluval "M" series, the reflective technology equipped in these heaters helps maintain the aquarium's natural look by reflecting the colors of the surroundings.

Fluval's pioneering spirit dates back to 1975 when the company introduced the world's first 3-stage filter with synchronous motor technology, a landmark breakthrough that is still applied in the industry today. Since then, Fluval has built a legacy around this innovative approach, continuously adapting to launch cutting-edge aquarium products that set the bar in quality, style, and functionality.

Beyond its manufacturing role, Fluval takes pride in its charitable and educational efforts, giving back to the fishkeeping community. The company has helped fund the protection of wild coral reefs and documented endangered fish species worldwide, inspired by a mission to not just build products that mimic the natural world, but to inspire aquarists of all skill levels to enjoy and respect the hobby for generations to come.

The Fluval M50 Submersible Heater boasts a modern aesthetic, combining sleek Italian construction with reliable performance. The ultra-slim profile of these heaters sets them apart from traditional, bulkier designs, making them a welcome addition to any aquarium setup.

The reflective Borosilicate glass tube that encompasses the heater is heat-and-shock resistant, allowing it to blend seamlessly with the aquarium's environment by reflecting the surrounding colors. This enhances the overall aesthetics of the aquarium, creating a natural and visually appealing display.

The computer-calibrated thermostat on the Fluval M Submersible Aquarium Heater features an easy-to-adjust temperature control dial and a blue on/off indicator light to ensure optimal temperature control and monitoring. The ultra-slim design also allows for easy installation within the aquarium tank.

The Fluval M50 underwater heater is recommended for freshwater and saltwater aquariums up to 15 gallons, and each M-Series heater comes with a 3-year limited warranty, ensuring exceptional performance and unsurpassed reliability.
