About this item
- [Titanium Aquarium Heater] Heater is made of heavy-duty titanium, water heats up faster and is completely shatterproof because there is no glass in the construction. Suitable for saltwater and marine aquariums from 400 to 550 liters.
- [Accurate Temperature Detection] The temperature probe is integrated on the top of the heater to detect the water temperature more accurately, and the measurement resolution of 0.1℃, Accuracy:±1℃.
- [LED External Controller with Indicator] Adjustable temperature range: 0°C-40°C/32°F-104°F. Fahrenheit and Celsius can be converted to each other. Dual digital display window clearly shows the water temperature and set temperature. When the water temperature exceeds the set temperature, the heater will automatically stop heating and the red heating indicator light will go out. When the water temperature is 1℃ below the set temperature, the heater will heat up automatically.
- [Easy to Install] There are two sturdy suction cups on the back of the heater to fix it horizontally or vertically to the glass aquarium, ensuring smooth operation of the heater in the aquarium.
- [Precautions for use] Please note: Submersible fish tank heater must be fully immersed in water, exposure to air may cause loss of temperature control, and do not bury them in sand or mud.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
