YOFOTHS offers quality aquarium equipment and services. Every product undergoes rigorous testing and inspections to ensure high quality. The 10W, 20W, 30W, 50W, 100W, and 200W Aquarium Heaters are equipped with an algae scraper and water pumps.

Operation: Press the SET button to adjust the target temperature between 64-93°F. The external controller is not waterproof. To change the temperature unit between C and F, press and hold the 'SET' button while powering on the heater.

Cautions: The surface and LED screen of the heater must be cleaned with a soft brush when dirty. Disconnect the power outlet and wait 15 minutes before changing the water or removing the heater. Do not bury the fish tank heater in the water. If the ambient temperature is low, use a powerful heater or two heaters. If the water temperature is lower than the ambient temperature, wait for a few hours as the temperature will increase slowly.

Protection: The heater has an "E1": out of water protection and "H1": overheating protection. A moderate size fish tank heater is recommended as too small or large of a heater can cause issues.

Additional Features: The digital controller is easy to operate, and the current temperature is directly displayed on the LED screen. The upgrade chip allows for quick response after sensing the water temperature.
