Hygger Digital Mini Aquarium Heater

Hygger Digital Mini Aquarium Heater

Precise heating for a nano tank.

The Hygger Digital Mini Aquarium Heater holds temperature in small tanks for fish and shrimp. An LED display shows the current water temperature and your set point, and the slim body tucks in behind plants or hardscape.

Key Features:

• Bright LED Display: Shows real-time water temperature and your set point.

• Touch-Button Precision: Adjusts from 68-94°F (20-34°C) in 1° steps.

• Intelligent Thermostat: Maintains ±0.5°F accuracy.

• Advanced Safety: Overheat and dry-run protection shuts the heater off if it is exposed to air.

• Shatter-Proof Quartz Tube: Equipped with a removable guard to protect fish and shrimp.

• Flexible Installation: Slim profile mounts vertically or horizontally with twin suction cups.

Why Choose Hygger?

Set the temperature in 1 degree steps and the thermostat holds it to within half a degree Fahrenheit. Two sizes cover tanks up to 40 L. The body is short enough to hide behind planting, which matters in a nano tank where a full-length heater has nowhere to go.

Installation Tip:

Place the heater near a filter outflow so the warm water spreads through the tank instead of pooling in one corner.
