Do not energize the heater before it enters the water. The heater heats up extremely quickly in the air. If you are not careful, you may burn your hands. When the temperature is high, it will be broken.
Your child may be interested in the knob on the thermostat. If the knob does not have a protective cover, after adjusting the temperature, the knob can be removed.
The heater is a device that must be purchased to raise tropical fish.
For the north in the very cold winter, the goldfish should also be prepared with heaters. Otherwise, temporary negligence, such as temporary suspension of heating, will cause unnecessary losses.
Aquarium heaters do not cost much, because tropical fish have a natural temperature of 24 to 28 ° C. The temperature is low while maintaining a suitable temperature. Once the temperature reaches the required level, the power consumption is even less.
Most of the heaters used in the home are single small heating elements. There are many varieties to choose from in the market, and there are many thermostatic control devices that are safe and reliable to use. Another benefit of the heater is that it is used to treat sick fish or to provide higher water temperatures for some fish to promote their reproduction.
Nowadays, small aquariums also have high-powered heaters, but if the performance of the heaters is not good, the danger is very high, especially when the heater is in an abnormal "work", the water will heat up very quickly. Even boiling and dying your fish, high temperatures can cause the glass jar to burst. Moreover, the smaller the aquarium, the faster the temperature changes. If the heater is too large, it will start and stop frequently, which will easily damage the thermostatic control components and cause the heater to malfunction. In contrast, large aquariums with low-power heaters can only reach their maximum load, and when the ambient temperature is too low, it is useless.
