About this item
  • 【Material】The submersible aquarium heater is made of explosion-proof quartz glass, comes with a highly temperature-resistant nickel chromium heating wire, and a heat conductor made of magnesium powder-safer;Features a Fahrenheit/Celsius switching function (displayed as FFF for Fahrenheit and CCC for Celsius).
  • 【Temperature Calibration Function】Small Fish Tank Heater Features an integrated temperature calibration mechanism for enhanced measurement accuracy. To activate, first hold down the up key while disconnecting the power cable, then reconnect it. Upon the display showing “HO1”, the calibration function will commence. Use the up and down keys to adjust the temperature value. After setting the desired temperature, calibration is complete once the display stops flashing after several seconds.
  • 【Dual Heating Modes】 The mini heater for fish has two operating modes – Precision Mode and Energy-Saving Mode. In Energy-Saving Mode, the heating function activates when the temperature falls 1°C (1°F) below the setpoint. In Precision Mode, the heating function engages when the set temperature exceeds the current temperature by 0.5°C/°F.
  • 【Temperature Setting】 Adjustable aquarium heater, press and hold any button on the side of the controller for 3 seconds. The digits on the display will flash. Release the button to enter temperature adjustment mode. Press the up button to increase the set temperature; press the down button to decrease it. The temperature setting range is 59°F–93°F/15°C–34°C. Once the target temperature is selected, the setting will be automatically saved if no further operation is performed within 3 seconds. Temperature setting complete.
  • 【Maintenance and Cleaning】This turtle tank heater should be positioned in an area of strong water flow or at the water inlet, at an angle of approximately 30-45 degrees. Do not bury the heating rod in the substrate or place it near the gravel bed during use. It is recommended to clean the water level detection area approximately every three months, wiping away any attached algae or debris. (Accumulation of algae or debris may cause the heating rod's power cut-off function to fail when exposed).

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.
