【Safety And Stability】: DaToo Flat Fish Tank Heater adopts PTC ceramic heating structure, which can quickly and accurately warm aquarium water up to 5~9℉above ambient room temperature. When the water temperature rises, the power will automatically reduce to avoid overheating and maximize the safety of your fish. When the temperature decreases, the power will gradually increase to ensure that the water temperature is always stabilized at a comfortable temperature, energy efficient.
