MantaMaze Aquarium Heater 300W-1000W for 20-300 Gal | Auto Stop & Overheat Protection

Smart, reliable heating for your aquatic world

Introducing the MantaMaze Aquarium Heater, upgraded for dependable warmth in both freshwater and saltwater setups. Built with two robust heating tubes crafted from explosion-proof quartz glass and nickel-chrome wires, it distributes heat evenly and helps maintain a steady environment for your fish and plants. The sturdy shell uses flame-retardant plastic that resists corrosion and heat, while also keeping curious fins away from hot surfaces for peace of mind in busy tanks.

Designed for convenience and safety, this heater features an external digital controller. You can read the current water temperature, set a target, and monitor warnings without getting your hands wet. The interface uses clear LED indicators: a red light signals active heating, while green confirms the target temperature has been reached. An audible alert and error codes trigger if a fault is detected, helping you respond quickly.

Precise, user-friendly control

The temperature range is adjustable from 63–94°F (average 17–34°C), with ±1°F precision to suit your ecosystem. Hold the “+” and “–” for 5 seconds to switch between Fahrenheit and Celsius, and rely on the memory feature to retain your preferred setting after a restart. This means fewer tweaks as you observe your tank’s daily rhythms.

Versatility for many setups

Available in 300W, 500W, 800W, and 1000W, this heater is designed for tanks from 20 to 300 gallons. It’s suitable for a wide range of environments, including freshwater, saltwater, and even certain turtle habitats.
