加热棒使用注意事项：
Cautions for the use of heating rods:
1、鱼缸加热棒在空气中切勿通电。因为其在空气中升温极速，轻则烧坏加热棒，重则炸碎玻璃或烧伤手。即使断电后也不能立刻从水中拿出来，这时候的温度也是非常高的，同样容易烫伤人和烧坏加热棒
1. Do not electrify the heating rod in the air. Because it warms up very quickly in the air, it burns the heating rod slightly and breaks glass or burns hands heavily. Even if the power is cut off, it can not be taken out of the water immediately. At this time, the temperature is very high. It is also easy to burn people and burn heating rods.
2、换水时注意不要使水位过低露出加热棒。
2. Be careful not to expose the heating rod when changing water.
3、注意鱼缸加热棒的寿命。
3. Pay attention to the life of heating rod in fish tank.
4、经常观察加热棒和温度计，加热棒的指示灯并不能表示正常工作，应以水温为准。因为经常指示灯亮着，而加热棒并不在工作。
4. Observe the heating rod and thermometer frequently. The indicator lamp of the heating rod can not indicate the normal work, and the water temperature should be taken as the standard. Because the light is always on and the heating rod is not working.
