hygger Aquarium Heater, 50W/100W/150W/200W Adjustable Power Fish Tank Heater with Auto Power-Off and High-Temp Protection, Upgraded Titanium Turtle Tank Heater for Saltwater and Freshwater

About this item

• Adjustable Power: This aquarium heater allows easy power adjustment—press and hold the setting button to switch between 50W, 100W, 150W, and 200W. It fits all aquarium sizes, from small desktop ones to large tanks, and adapts to different seasonal needs. This all-in-one design saves you extra costs
• All-Round Safety Protection for Your Aquarium Heater: It has a dual temperature control system—if one system malfunctions, the other will automatically activate to prevent overheating and "cooking" the fish. Furthermore, it has double-sided water shortage protection: it automatically stops heating when out of water to avoid dry burning, and restarts once submerged again. Suitable for horizontal installation in low-water-level aquariums; especially suitable for frog, salamander and turtle tanks
• ±0.5°F Precise Temperature Control: This fish tank heater provides accurate temperature control to within ±0.5°F, keeping your aquarium water consistently stable. If it keeps heating slightly as it nears your set temperature, don’t worry — this is completely normal for its high-precision design. The included external controller lets you easily adjust the target temperature from 59–93°F. Ultra-precise heating ensures your fish are healthy and happy
• Premium Titanium Heater: This fish tank heater is made of high-quality titanium, which is more corrosion-resistant, explosion-proof, safe and durable than other materials. Its large-area titanium heating element enables faster, more uniform heating for stable water temperature, while the thickened ABS shell further enhances its durability, making it ideal for long-term use in both saltwater and freshwater fish tanks
• User-Friendly Design & Easy Installation: Featuring reliable dry-burn protection, this fish tank heater automatically shuts off when the temperature exceeds 97°F, effectively avoiding overheating risks and keeping your aquatic pets safe at all times. It is simple to install with strong suction cups for a firm hold, preventing the heater from being moved by active reptiles for stable and worry-free use.
