Once the selected temperature is reached, the heater automatically stops heating and resumes when additional heat is required.

The quartz construction provides improved resistance to damage compared with conventional glass heating elements.

Its protective ABS casing provides an additional barrier between the heating element and aquarium inhabitants.

The Hygger Black Hole Heater includes several integrated safety functions designed to support reliable operation.

• Overheating Protection – Automatically shuts off heating if excessive temperatures are detected.
