Description

The Hydor Internal Aquarium heaters are capable of accurately maintaining the water temperature in your aquarium tank.

These shatterproof and fully submersible heaters can be placed in any position under the water, vertical or horizontal. Regardless of the position, the heaters work effectively to heat and maintain the temperature of the water.

The heaters have an easy to use thermostat dial on the top, simply set to the desired temperature and place in the tank. The heater will start to work and a light will appear to show it is working and heating the water the the temperature required. Once the desired temperature is reached, the heater will maintain that level.
