More Info

If you're in the market for a mini aquarium heater, you might want to check out the hygger 50W Mini Submersible Digital Display Aquarium Heater. This compact little heater is perfect for small tanks, ...with a size 50W version suitable for tank sizes up to 6.5 gallons, while a 100W model can handle up to 13 gallons.

The temperature accuracy is also impressive, with a 1℉ deviation. When you reach the desired temperature, the digit on the controller will flash three times to indicate that the setting is complete. However, do bear in mind that the controller is not waterproof, so you'll need to be careful not to get it wet. One unique feature of the hygger aquarium heater is the digital display panel. When the heater is heating your tank, an indicator light above the digital display comes on, and the display panel itself will show the current water temperature. You can also use the controller to display the temperature setting, but only when you press the button. The aquarium heater is equipped with a reliable thermostat to ensure that it maintains the desired temperature accurately. The heater only heats the water when the temperature is 1℉ lower than the set temperature, and stops heating once it reaches the set temperature. If the water temperature exceeds 95℉, the aquarium heater will automatically shut off and display "HH" on the temperature controller. It will resume normal operation once the temperature drops to below 95℉. Finally, the hygger aquarium heater is fully submersible, making it suitable for both saltwater and freshwater tanks. However, if the top of the heater is out of the water, it will automatically shut off and display "E1" on the controller. The heater will only resume normal operation when it's safely back in the water. In conclusion, the hygger 50W Mini Submersible Digital Display Aquarium Heater is an excellent choice for small aquariums.
