- Position the Heater:
- Attach the suction cup to the heater and then to the inside wall of your aquarium.
- Ensure the heater is completely submerged in water. The entire heating element must be covered by water.
- For optimal heat distribution, place the heater near a water flow source, such as a filter outlet, if available.
- Connect to Power: Once the heater is securely placed and fully submerged, plug the power cord into a suitable electrical outlet. Ensure a drip loop is created to prevent water from reaching the outlet.
5. Operating Instructions
The DaToo 25W Mini Aquarium Heater is designed for automatic operation, requiring no manual temperature adjustments.
- Automatic Temperature Control: The heater is pre-set to maintain a constant water temperature of 78°F (25.5°C). It will automatically activate when the water temperature drops below this level and deactivate once 78°F is reached.
- Indicator Lights:
- A red light indicates that the heater is actively heating the water.
- A green light indicates that the water has reached 78°F, and the heater has stopped heating.

- Monitoring: Regularly check the thermometer sticker to confirm the water temperature. While the heater is designed for precision, external factors can influence tank temperature.
6. Maintenance
Proper maintenance ensures the longevity and efficiency of your aquarium heater.
- Cleaning: Disconnect the heater from the power supply and allow it to cool completely before removing it from the water. Gently wipe the heater's surface with a soft cloth to remove algae or mineral deposits. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the power cord for any signs of damage or fraying. Check the suction cup for secure attachment.
- Water Changes: Always unplug the heater during water changes to prevent it from operating out of water. Wait until the tank is refilled and the heater is fully submerged before plugging it back in.
