Hygger Submersible Fish Tank Water Heater for Aquaria

Dual Temperature Control System One chip with two independent heating systems ensures reliable fish tank temperature regulation. Even if one heating rod fails, the other can continue to function, significantly reducing the risk of frozen fish and maintaining consistent tank conditions.

Controllable Heating Speed Each heating tube operates independently, offering precise temperature control within the range of 64-93℉. The heating process is evenly distributed around 360° with 20 nickel-chromium electric heating wires, allowing for adjustable heating speed and power.

Easy to Operate The full immersion heater has triple suction cups for secure installation in any corner of your fish tank. Its outward shell can be easily slid away for convenient cleaning. Adjust the temperature by rotating the top knob, and a sealed, waterproof plastic design protects the internal chip, enhancing durability.

Accurate Temperature Control Two built-in temperature probes monitor the water temperature in real-time, automatically stopping heating when the set temperature is reached and resuming when it drops. Temperature control errors are maintained within ±1°F, ensuring optimal tank conditions.

Versatile Compatibility Suitable for various types of fish tanks, including seawater, freshwater, and turtle tanks. A 600W model is ideal for tanks of 66-132 gallons, while the 800W model is perfect for tanks ranging from 80-220 gallons. Ensure complete submersion and avoid placing it on sand and gravel during installation.
