Compared with people, Aquarium fish are more afraid of catching cold and catching cold. If we humans catch a cold, we can take some medicine and wear more clothes. But what if our Aquarium fish catches cold? You can't give it a woolen coat, can you?

Fish are cold-blooded animals that do not regulate their body temperature on their own, so they can only rely on the heat provided by the external environment to keep warm and increase their body temperature. Therefore, our fish tank must have heating equipment.

Heating fish tanks can inhibit the growth of bacteria and accelerate the decomposition of spoilage substances, so heating fish tanks can prevent the occurrence of white spot disease and water mold. In the previous fifth bullet, I have already mentioned the method of warming up to treat white spot disease and water mold, so I won't go into more detail here.

Heating up the fish tank can help fish grow better and avoid the problem of fish not growing, developing, or reproducing in winter. The heating of the fish tank is also an essential device for newborn fish fry.

Types of heating rods

There are currently many types of fish tank heating rods on the market, and I would like to introduce the mainstream ones to you.

Glass heating rod

The glass heating rod has a simple structure, reasonable price, and good thermal conductivity. Its disadvantage is that the material is particularly brittle, afraid of touching, falling, and dry burning, and is particularly prone to cracking when suddenly exposed to water after heating. The glass heating rod has gradually withdrawn from the market. Taking into account all aspects of performance, my recommended index for glass heating rods is 60 points.

Stainless steel heating rod

Stainless steel heating rods have excellent thermal conductivity, are sturdy and durable, and are not expensive. They are commonly used by most fish enthusiasts. But it is not corrosion-resistant and cannot be used in saltwater tanks, especially in seawater tanks. The use of stainless steel heating rods for a long time will release metal ions and pollute water quality. Stainless steel heating rods are relatively safe, but it does not mean that there will be no problems. Taking into account all aspects of performance, my recommended index for stainless steel heating rods is 70 points.
