Hygger Vertical Aquarium Heater for Saltwater and Freshwater Fish

Submersible Fish Tank Spare Heater: hygger 200w/300w Vertical Aquarium Heater

Why do fish need an aquarium heater? Fish are cold-blooded animals, unable to regulate their body temperature like humans and other mammals. Whether in the sea or an aquarium, they require the proper external temperature to survive. The aquarium is an artificial environment, not the natural habitat for fish, so the aquarium owner must work harder to maintain the correct water temperature.

The hygger aquarium heater features a top monitoring probe that detects water temperature and heater status in real-time, without risk of entanglement or leakage. The high-quality material shell has small gaps to prevent fish blockage. An LED indicator displays heating (red) and stopped (green) status.

Designed in a vertical orientation with a stable chassis, the heater allows accurate temperature selection between 60°F and 90°F via the external controller, providing a safe and simple control interface. The flexible 3.28ft+6.2ft power cord accommodates most applications.

Key product advantages include E1 Anti-Dry Protection, 96°F Over Temperature Protection, and Short-Circuit Protection. If any issues occur, a backup circuit in the controller will shut off the heater and display the fault code, ensuring a warm and safe environment for fish.

The heater is constructed with explosion-proof quartz glass and high-temperature resistant nickel-chromium heating wire, delivering a long service life and uniform heating. White sand fill enhances thermal conductivity. The constant temperature protection reliably maintains the set water temperature.

The detachable suction cups allow placement in various directions, and the vertical design enables use as a supplementary heater in bottom filter tanks. Suitable for both saltwater and freshwater aquariums, the heater offers fast heating, corrosion resistance, and oxidation resistance.

The external controller allows easy temperature adjustment between 60°F and 90°F, with ±1°F accuracy, without worrying about wet hands. When the water temperature exceeds the set value, the heater automatically stops, and the green indicator light turns on. If the temperature drops below the set point, the heater restarts, and the red light illuminates.

In addition to the multiple safety protections, the digital display shows settings, real-time temperature, and any error codes. The vertical shape, supported by a base, provides flexible installation options to meet different tank requirements.
