HANLESHUKA 100W Aquarium Heater for 10-20 Gallon Tanks | Auto Shut-Off, Dry-Burn & Overheat Protection

Steady, Safe Heating for Small Tanks

Keep your 10–20 gallon freshwater, saltwater, or brackish tanks consistently comfortable with the HANLESHUKA 100W Aquarium Heater. Fully submersible and designed for reliability, it features an auto shut-off when the heater leaves the water and an audible alert, so you’ll know immediately if water levels change. When re-submerged, it resumes heating at your set temperature without needing extra tweaks—helping you maintain a stable environment for your aquatic life.

Smart safety you can rely on

• Dry-burn prevention automatically cuts power when out of water to minimize risk.
• Overheat protection stops heating if the water climbs 1°F past the target.
• Max temperature auto stop clamps the heater at the chosen limit, even if the controller fails.

Precise, at-a-glance control

• External digital controller shows real-time temp and target simultaneously for quick checks.
• Red indicates active heating; green signals when the set temperature is reached.
• Intelligent power output adapts to maintain stable temperatures with fewer swings.

Seashell guard design for safety and flow

The seashell-pattern guard surrounds a 2mm quartz glass heating element, promoting even heat distribution while directing water flow. The guard provides a physical barrier to help protect curious fish and turtles from hot surfaces, and it resists corrosion in both freshwater and saltwater setups.

Easy setup for any tank

• 100W is ideal for 10–20 gallon tanks; other HANLESHUKA models cover larger ranges (200W, 300W, 500W).
• Fully submersible and compatible with glass or acrylic tanks.
• Place with suction cups, set your temperature, and switch between Fahrenheit and Celsius with a long press.

In real-world use, this heater supports a straightforward routine: mount it, monitor the display from across the room, and rely on safety features during water changes or evaporation. The combination of simplicity, safe design, and responsive temperature control helps you focus on your tank’s inhabitants rather than the equipment.
