About this item
- 【Dual LED Digital Temperature Display】 Both the aquarium heater and controller feature this display, providing clear synchronised readings with matching indicator lights for enhanced visibility. Water temperature can be easily set and monitored. When the display flashes, adjust to the desired temperature. Once set, the display will show the current temperature steadily without flashing. Press the “SET” button at any time to view the saved settings.
- 【Memory Function & Power Failure Protection】 Upon power restoration, the submersible fish tank heater automatically retains the previous settings. Heating ceases automatically upon reaching the set temperature. The unit shuts down automatically during low-water operation to prevent equipment damage.
- 【Intelligent Temperature Control System】 Fish Tank Heater, automatically cuts power upon contact with air (dry-burn protection). The LED display flashes “Er” and shows the current temperature. When the temperature reaches 97°F (36°C), it triggers automatic power cut-off and displays “EE”.
- 【Explosion-Proof Quartz Heating Tube】 This turtle tank heater features an integrated explosion-proof insulated design with compact dimensions suitable for small aquariums. Compatible with both freshwater and saltwater aquarium environments.
- 【Usage】The heater must be fully submerged in water during operation. Ensure adequate water flow and circulation within the aquarium. The red indicator light signifies heating status, while the green indicator light indicates standby mode (not heating).

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

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.
