Hygger 300W Aquarium Heater | Intelligent Temperature Control for 40-75 Gallon Tanks | Safe & Efficient

Reliable heating for large tanks

The Hygger 300W Aquarium Heater is built for 40–75 gallon tanks in both saltwater and freshwater setups. It blends sturdy materials with thoughtful design to help you maintain steady warmth without excessive effort.

Durable, safe construction

A robust explosion proof quartz glass housing teams with a high temperature nickel chromium wire and silicon carbide to deliver consistent heat while staying resilient under routine use. The protective ABS shell adds a layer of safety during handling and maintenance.

• Explosion proof quartz glass housing
• High temperature resistant nickel-chromium heating wire
• Silicon carbide for efficient heat transfer
• Sturdy ABS shell for protection in busy tanks

Smart protections for peace of mind

Multiple safeguards are built in to help you keep tank temperatures within a comfortable range. The heater stops automatically when the target is reached, and an audible alert can signal if temperatures approach the limit. There is power off when out of water to prevent dry burn, and a side probe enhances monitoring and quick response.

• Over temperature protection with alert
• Auto shutoff when water level drops
• APS anti boiling system reduces risk of runaway heating

Energy efficiency and simple control

The external controller is easy to use, with temperature adjustments in small steps. As the target nears, the heater reduces power to conserve energy while using thermal inertia to approach the setting smoothly. The 59–93°F range suits diverse species.

• Automatic low power near target helps save energy
• Fine 0.5°F adjustments for accurate tuning
• Compatible with both saltwater and freshwater tanks

What’s in the box and reliable support

Each package includes 1 heater, 1 controller, and 2 suction cups. A 24-month warranty accompanies the product, with responsive after sales support to help with setup or questions.
