Fashionable Fluval Submersible Glass Aquarium Heater, 50-watt

Keep your fish happy, healthy and swimming in comfort with the Fluval Submersible Glass Aquarium Heater. This sleek and compact submersible heater provides exceptional performance and unsurpassed reliability in both fresh and saltwater tanks. Made from high-density ceramic, the heating element is encased in shock-resistant borosilicate glass and features a temperature range of degrees F. To help maintain the aesthetics of your aquatic display, the unique reflective technology of the outer casing makes the heater virtually invisible in your tank. For your convenience, dual suction cups allow you to easily install it inside your aquarium.

Water level should not rise above the maximum water line or below the minimum indicated on the glass heater tube. Always maintain the water level in the aquarium to compensate for water loss due to evaporation.
