About this product
This submersible aquarium heater runs at 200W and AQQA sizes it for tanks of 45 to 80 gallons. It measures 28.4 x 5.4 x 2.5 cm and works across a temperature range of 68°F to 93°F, set from an LED controller that sits outside the water. The heater body goes in the tank and the controller stays dry.
What to check before you buy this heater
Check your tank volume first: the 200W rating is given for 45-80 gallon tanks, so a tank outside that band is a different size class. The heater body is 28.4 cm long and 2.5 cm deep, so measure the space where you plan to place it, behind or beside the filter, against those figures.
The controller is not waterproof and has to be kept away from water, which means the cable run between the tank and the point where the controller rests needs checking. A hook on the back of the controller adjusts to fit the thickness of your fish tank, so check the rim or frame it will hang on.
Heating parts, controller display and indicator lights
- The heating element is nickel-chromium heating wire built to resist high temperatures, with silicon carbide for heat conduction, and the outer shell is high-temperature resistant PC material.
- The LED controller shows current water temperature on the top line and the set temperature below it, and a built-in thermometer provides the reading.
- A red light marks heating, a blue light marks constant temperature, and a blue flashing light means the heater is not fully submersed.
- The controller keeps the temperature setting in memory when power is shut off.
Questions buyers ask before ordering

How long is the heater, and what is the model number?

How do I switch the display between Celsius and Fahrenheit?
Press and hold for 5 seconds to change the temperature display from Celsius to Fahrenheit.
Where does the controller go, and can it get wet?
The controller is not waterproof and must be kept away from water, and the hook on its back adjusts to fit the fish tank thickness.
How the heater runs in the tank
The heater switches itself on once the water is 1°F below the set temperature and stops when the water reaches it. If the heater sits 5 cm above the water surface, it powers off and shows E1 on the controller; once it is submerged again it returns to normal, with no unplugging or reset needed.
The heating wire takes 2 hours to raise the water temperature by 1°C. Keep the controller clear of water at all times.
