MantaMaze Aquarium Heater 300W-1000W for 20-300 Gal | Auto Stop & Digital Controller

Reliable warmth for your aquatic world

Designed for tanks from 20 to 300 gallons, the MantaMaze Aquarium Heater line delivers steady, dependable warmth with a focus on safety and ease of use. Available in four wattages—300W, 500W, 800W, and 1000W—you can pick the option that best fits your setup. The heater’s dual quartz heating tubes are built with explosion-proof glass and nickel-chrome wires, promoting even heat distribution and a rapid response time to keep your fish, plants, and in-tank ecosystems comfortable.

The shell uses a V0-rated flame-retardant plastic that resists heat and corrosion, and its safe design keeps contact with hot components minimal, reducing risk and making maintenance simpler. In practice, this means fewer interruptions and more time enjoying your aquatic display.

Smart safety and control at a glance

Safety features are embedded to protect your tank. If water temperature rises above 94°F or the top of the heater is not fully submerged, the unit automatically cuts power and displays an error code with an audible alert until conditions return to safe levels. The external LED controller shows current temperature, the preset target, and warnings for high temperature or out-of-water conditions, so you stay informed without reaching into the water.

The red indicator signals active heating, while the green indicator confirms the target temperature has been reached, giving you clear feedback at a glance.

Precision, flexibility, and ease of use

The temperature range spans 63-94°F (19-34°C) with ±1°F accuracy. Switching between Fahrenheit and Celsius is straightforward, and the memory function retains the last setting after restart so you don’t have to reconfigure each time you power up. This combination of precision and convenience helps create a stable environment for your aquatic life and décor alike.

Versatile installation for any setup

Whether you keep freshwater, saltwater, or turtle tanks, this heater adapts to diverse environments. It mounts to the tank wall using the included suction cups, preserving the tank’s style and decorations. The external control minimizes water contact, making routine checks quick and clean.
