Versatile heating for any tank

With a simple, intuitive design, you can pick the size that matches your tank and stocking needs.

Smart, energy-conscious heating

Smart heating uses a stair-step approach: when the red light is on, the unit is actively warming toward the set point; when the green light is on, it maintains the temperature. An additional thermometer is included for real-time checks, so you can monitor warmth without guesswork.

• Six sizes to match different tank volumes
• Two indicators: red for heating, green for maintaining temp
• Free thermometer included for real-time monitoring
• Durable heat-resistant ABS outer shell
• Nickel-chromium heating wire for faster response
• Quartz glass protection for safety and longevity

Real-time monitoring and quick responsiveness

In addition to built-in controls, the thermometer supports ongoing checks, helping you keep track of water warmth as plans change from feeding to water changes.

• Real-time temp checks aid tank management
• Fast response helps you reach target temperatures more predictably

Durable, tank-ready construction

The outer shell uses heat-resistant ABS to resist deformation under heat, while the heating element relies on a nickel-chromium wire and non-corrosive quartz glass for reliable operation in humid environments.

Safe operation and easy maintenance

Safety-focused usage tips help you keep things running smoothly. Always ensure the heater is fully submerged before powering on. When cleaning or performing water changes, unplug and allow the unit to cool for 10–20 minutes.
