? The 25w heating rod can only be used for the smallest size of the fish tank, with a volume of less than 12 liters. If you use a big fish tank, the heating time will become very long, which will consume more electricity. It should be noted that the power of the heating rod can be larger, so that the heating speed is faster, and it will be closed after reaching the target temperature, so there is no need to worry about the continuous heating affecting the health of fish.
for the heating rod? 1. Power on in the water: The heating rod must be placed in the water before it can be powered on. Do not let it heat in the air, because the heating speed is very fast, which will cause the heating rod to be burned out, and even break the glass in serious cases. In addition, it can not be taken out immediately after power failure, and it needs to be cooled before it can be taken out.
2. Placement position: The heating rod is generally placed horizontally in the fish tank, and it should be lower, so that the heating speed is faster, and the water below will rise after heating, thus increasing the overall temperature. In addition, when changing water, we must pay attention not to let the water level be lower than the position of the heating rod.
3. Service life: The heating rod, like other equipment in the fish tank, also has a service life. For example, the heating rod of the bimetallic strip should be replaced in one or two years, otherwise the equipment will fail or even leak electricity. At ordinary times, we should also pay attention to its indicator lights to see if it can work properly.
