 Power: 50 W suitable for small-volume aquaria
 Length: 15 cm compact immersion tube
 Construction: Corrosion-resistant outer sheath suitable for freshwater
 Operation: Designed for continuous use with steady output
How to use
Mount the Hagen Marina Mini vertically or horizontally inside the aquarium where water flow can distribute heat evenly but away from direct contact with substrate and delicate plants. Submerge the heater completely before switching on the power and verify that the indicator (if present) functions. Allow the heater to run and reach the target temperature gradually; check the aquarium thermometer to confirm stable readings. For maintenance, disconnect power before removing the heater and follow regular cleaning to prevent buildup on the outer sheath.
Usage recommendations
Place the heater near gentle circulation from a filter or powerhead to ensure even temperature distribution. Use an external aquarium thermometer to verify set temperatures and avoid rapid thermostatic adjustments. For very small tanks, consider the 50 W capacity relative to ambient room temperature and lighting to prevent overheating; reduce risk by monitoring water temperature regularly.
