Product Features
- Overheating protection
This 300-watt fully submersible aquarium heater features built-in overheating protection and memory function. It will automatically shut off when overheating is detected and reset automatically once the temperature returns to safe levels.
- Resistant to explosion and corrosion
Made with premium quartz and double sealed by the black protective casing, this fish tank heater is resistant to explosion and corrosion, which can protect fish and other livestock from punching and scalding.
- Built-in external IC temperature controller
The aquarium heater features an easy-to-read blue LED digital display that provides real-time water temperature readings. The heating indicator light turns red when the heater starts to heat and turns yellow once the set temperature is reached. The heater offers temperature accuracy within a range of ± 1°F.
Directions for Use
- How to Set Temperature?
1. Place the heater rod and temperature probe in the aquarium, ensuring both are completely submerged.
2. Connect the heater to a power source to activate the blue LED digital display, which shows the current water temperature and the red indicator light is on.
3. Press the “Set” button to set your desired temperature. The display will blink for 3 seconds to confirm, and then the heater will begin to warm the water.
4. When the set temperature is reached, the red indicator light will change to yellow.
- Useful Tips
1. Ensure the 300-watt heater does not come into contact with sand or gravel on the aquarium floor.
2. Position the heater near the tank filter for optimal performance and to prevent overheating.
3. Do not operate the aquarium heater unless it is fully submerged in water.
4. Always unplug the heater before changing the water in the tank.
5. Before using the heater, carefully read the instructions and warnings on the packaging.
6. Maintain the heater rod and temperature probe in a fully submerged state at all times.
7. Before changing the water, cleaning the tank, or removing the heater, disconnect the power supply and allow the heater to cool for 15 minutes. Failure to do so may result in the high-temperature heater rod melting the protective casing.
Nice little heater. I used it on my 40 breeder tank. It maintained the temp really well. It’s small and black in color which makes it blend in the background. You can see the comparison in size in the photos.
Having the controller outside the tank makes it much easier to change the temp in case you have to.
