Description
If you are dealing with inconsistent temperatures in a freshwater tropical aquarium, this submersible aquarium heater with an external LED thermostat gives clear, controllable heating. The external controller allows precise adjustment between 15°C and 34°C and displays both the current water temperature and the set temperature, so you can monitor conditions at a glance. The 75W option is one of several wattages available to suit different tank sizes.
The heater uses an intelligent thermostat that activates heating when the water drops below the chosen set point, helping to reduce temperature swings. An explosion-proof quartz tube with a protective cover offers corrosion resistance and impact protection while lowering the risk of burns to fish. It is fully submersible, includes a 1.5 m power cord and suction cups for vertical or horizontal mounting, and will automatically resume the previous temperature after a power interruption. For safe cleaning, disconnect power 15-20 minutes in advance and allow the unit to cool in water before removing.
