hygger Mini 75W Submersible Heater for 10-15 Gallon Aquariums | Digital Display & Adjustable Temperature

Effortless Climate Control for Small Aquariums

Introducing the hygger Mini Fish Tank Submersible Heater, a compact 75W heater designed for 10-15 gallon aquariums. Its sleek black housing hides behind decor while delivering steady warmth for your fish and plants. The unit is easy to install and easy to read, making daily temperature checks simple.

For safety and reliability, this heater includes several built-in protections and prompts that help you monitor performance without guesswork. In the event of a fault or abnormal condition, an audible beep and fault prompt alert you right away. A low water level shutdown reduces risk, and overheat protection helps prevent overheating. An error code alarm provides a quick diagnostic path so you can address the issue promptly. Note: if a malfunction occurs and heat remains in the heating rod, the shell could soften; handle with care and unplug the unit to cool.

Precise, User-Friendly Temperature Control

• External thermostatic controller lets you set a target range between 59 and 93 degrees Fahrenheit.
• Digital display shows real-time water temperature at a glance for accurate monitoring.
• An indicator light reveals whether the heater is actively heating or on standby.

Smart, Dependable Heating You Can Count On

The hygger mini heater maintains a steady temperature by turning the heater on when the water falls below the set point and off when the target is reached. The memory function preserves your chosen temperature after power interruptions, so you don’t have to reset each time the power returns.

Easy Installation and Safe Operation

• Keep the heating rod fully submerged and use two suction cups to mount vertically or horizontally on the tank wall.
• Unplug before water changes and allow the heater to cool for about 15 minutes before handling.

Whether you keep a lively betta, small community fish, or shallow-tank turtles, this compact heater offers a discreet and reliable temperature companion. It’s designed to blend into your aquarium setup while providing consistent warmth, so your aquatic inhabitants can thrive with a stable environment.
