The power of the heating rod is relatively small. Generally, it will not electrocute people. The possibility of electrocuting fish is not great, but it will affect its normal growth. It should be noted that if the heating rod leaks electricity, it is better to replace it in time, otherwise there is still a certain risk. Usually in use, you need to put it in the water first, and then you can turn on the electricity to heat it. If you see something wrong with the fish, you need to turn off the power to check it in time.
the heating rod 1. Material: There are two kinds of heating rod materials, one is glass, the other is stainless steel. The effect of stainless steel is often better, because the thermal conductivity of metal is strong, so it is easier to heat up, but it is also easier to corrode, and it can not be used in seawater tanks.
2. Power: The power of the heating rod is generally related to the water contained in the fish tank. Usually, one liter of water corresponds to 1.5-2 W of power. If there is 300 liters of water, 500-600 W of heating rod is needed. The power of the heating rod determines its heating speed, and the power consumption is basically the same.
3. Safety: The safety of the heating rod is also a problem. If it is not used correctly, or if it is bought with inferior quality, there is often a risk of breakage, and some will leak electricity. So before buying it, you must look at the evaluation to ensure that it is safe to use.
