About this item
- [Mini Submersible Aquarium Heater]: 50W oval-shaped aquarium heater is designed for 50L fish tanks. Dimensions: ?75x110mm, it is easy to conceal within the tank. The power cord is 1.2M long, providing ample reach. Made of thickened plastic protective cover, anti-impact and anti-corrosion, featuring a high-temperature resistant nickel-chromium heating wire, this small aquarium heater ensures faster and more durable water heating.
- [Intelligent Over Temperature Protection]: This fish tank heater features an intelligent temperature system. It automatically stops heating when the temperature rises above the set limit, and resumes heating when it falls below the desired temperature. Additionally, it has an automatic power-off function when the heater is out of the water, ensuring maximum safety for both you and your aquatic organisms.
- [LED Digital Display]: This fish tank heater has an LED display located on the front side. During heating, the red indicator light above the digits will be lit, and when heating stops, the light turns off. The built-in thermometer continuously displays the water temperature on the LED screen. The heater remembers the temperature setting, eliminating the need to reset it after a power-off.
- [External Temperature Controller]: The aquarium heater is equipped with an external controller that allows you to set the temperature without needing to put your hands in the water or rotate a dial. This touch operated controller enables you to easily tap and set the desired temperature, ensuring you never wet your hands or contaminate your tank.
- [High Quality Heater]: Prior to powering on, fully submerge the aquarium heater in water, avoiding burying it in sand. Position the heater near the water loop exit, securely fasten it with suction cups horizontally or vertically close to the pump for efficient heat dissipation. They are designed for use in environments like fish tanks, aquariums, and small fish ponds.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
