1、 What size fish tank is suitable for a 25W heating rod

The 25W heating rod can only be used for the smallest size fish tank, with a capacity of less than 12 liters. If a large fish tank is used, the heating time will become very long, which is relatively more electricity intensive. It should be noted that the power of the heating rod can be higher, so the heating speed is faster. In addition, it will turn off after reaching the target temperature, so there is no need to worry about continuous heating affecting the health of the fish.

2、 What are the precautions for heating rods

1. Power on in water: The heating rod must be placed in water to be powered on. Do not let it heat in the air, as this heating speed is fast and can cause the heating rod to burn out, and in severe cases, even shatter the glass. In addition, it cannot be taken out immediately after a power outage, and it needs to wait for it to cool down before being taken out.

2. Placement position: The heating rod should generally be placed horizontally in the fish tank, and should be lower, so that the heating speed is faster, and the water below will rise when heated, thereby increasing the overall temperature. In addition, when changing water, it is important to be careful 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, has a service life. For example, the heating rod of Bimetal should be replaced in a year or two, otherwise the equipment will fail and even lead to electric leakage. At ordinary times, you should also pay attention to its indicator light to see whether it can work normally.
