## Description

Adjustable 50W Aquarium Heater Submersible Fish Tank Heater Super Short Aquarium Heater with LED Digital Display Thermostat, for Tanks 5-10 Gallons

## Features

- SUPER MINI SIZE – This aquarium heater is SUPER SHORT in length – might be the shortest heater in the market. It is only a bit more than HALF of the length comparing with the traditional fish heaters! The innovative super short length perfectly solves the headache of the fish keepers on the traditional aquarium heaters! Takes up less space, easy to hide, but in full power! Temperature range is 18-36℃.
- ACCURATE TEMPERATURE – Thanks to the intelligent inverter technology, with the in-built chips the thermostat keeps the heater at a constant temperature at an accuracy of 1F, much more accurate than the traditional knob-controlled fish heaters. The thermostat shows 2 readings – the current temperature and the set temperature – very easy to operate.
- DRY RUN / OVERHEATING PROTECTION – Full consideration of safety. With the multiple protections this fish tank heater will stop working when the water level is lower than the minimum water level (DRY RUN PROTECTION) or when the water temperature exceeds 36℃(OVERHEATING PROTECTION). You are free from “cooking fish”!
- MEMORY FUNCTION – The last setting is stored in the chips of the thermostat. In case of a power cut, when the power recovers the fish tank heater will follow the last setting.
- MULTIPLE USES – This fish tank heater can be used for both fresh and marine water. It can be not only used as an aquarium heater, but can also work a turtle heater, pet fountain heater, and plant seedling heater.
