As the temperature drops in winter, fish also need to keep warm in the fish tank. The common way to keep warm is to maintain the water temperature by heating. Nowadays, there are various temperature control devices, but there is no doubt that the heating rod is a The most common heating tool in the aquarium, it is also the easiest. In addition to ensuring that the fish can live in a suitable temperature, it is often used to treat sick fish or provide a higher water temperature for some fish to promote their reproduction.

1. Classification of heating rods

According to the material, it is divided into glass heating rods and metal heating rods

(1) The glass heating rod generally adopts the anti-riot glass shell, which has the characteristics of low price and wide range of use, and can be used in various aquariums. The disadvantage is that it is easily broken. If it is used in a large fish tank, it must be equipped with a protective cover to avoid damage to the fish. Generally, inferior heating rod glass is of poor quality and is more likely to be broken.

(2) The metal heating rod is generally made of stainless steel shell, which has the advantages of sturdiness, durability and texture. But the disadvantage is that some corrosive environments cannot be used, such as seawater tanks. Generally, inferior metal heating rods use iron shells to pretend to be stainless steel shells, which are easy to rust.

Second, the power of the heating rod

The common specifications of uncontrolled heating rods are 50w, 75w, 100w, 125w, 150w, 200w. The rod is simple, just wrap resistance wire around a ceramic tube and place it in a heat-resistant, waterproof glass tube. The wires are connected to the power supply through the waterproof sealant cover. Can be directly immersed in water for use. The non-temperature-controlled heating rod is mainly used to heat the water before changing the water in the fish tank. The heating rod using this power must be equipped with a thermometer, and the power should be turned off immediately to the required temperature.

The more advanced heating rods can control the temperature. Its power ranges from 50W to 1000W, and the common ones are 100W, 200W, 300W and 500W. This kind of heating rod can set the temperature in advance. When the water temperature reaches the preset temperature, the heating rod will automatically turn off. If the water temperature drops, the heating rod will automatically turn on heating until the water temperature reaches the standard.

Third, try to use low-power heating rods

If your aquarium is a small aquarium, it is not recommended to configure high-power heating rods, because if If the performance of the heating rod is not good, the danger is very great, especially when the heating rod is in abnormal work, the water temperature will rise rapidly, or even boil to cause the death of the fish, and the high temperature will cause the glass tank to burst. . Also, the smaller the aquarium, the faster the temperature rises. Excessive power heating rods will start or stop frequently, which can easily damage the temperature control elements and cause heater failures. If it is a large aquarium, it can be equipped with multiple low-power heating rods, and the final heating effect is the same.

In addition, the heating rod plays a role in keeping the water temperature in the aquarium constant and maintaining a temperature suitable for raising fish. It is very important in the aquarium. If the heating rod of the aquarium is used If there is a problem, it stops working, and it is not detected in time, and the fish raised are only sensitive fish such as arowana, then the arowana will definitely be uncomfortable due to the rapid drop in water temperature and the huge temperature difference, or even get sick. If the heating rod appears The problem is that the water temperature cannot be maintained at a constant value and is always in a heated state, then the fish will only be more dangerous. If it is not found in time, the situation of the fish will be very bad, and if the temperature of the heating rod is not ready, the same dragon Sensitive fish such as fish will only experience discomfort and disease due to chaotic changes in water temperature. Therefore, during the feeding process, be sure to observe the heating rod frequently and pay attention to the degree on the thermometer.
