• Operation: continuous heating for temperature stabilization

How to use

Mount the heater securely inside the aquarium according to the manufacturer's orientation recommendations, ensuring the device is fully submerged before switching on the power. Place the heater where there is good water circulation to distribute heat evenly throughout the tank. Set the desired temperature following any markings or controls on the unit and allow the aquarium to stabilise for several hours before introducing sensitive species. Periodically check the heater and tank temperature with a reliable thermometer to confirm consistent operation.

Usage recommendations

Use a separate aquarium thermometer to verify water temperature and avoid relying solely on the heater’s indicator. Perform routine inspections for glass integrity and cable condition, and turn off and remove the heater before any major maintenance or water changes if recommended by the heater documentation.
