1. the fish tank is open 24 hours to consume electricity?

The fish tank is open 24 hours to consume electricity, but in order to ensure the health of the fish, electricity can not be saved. Usually, the main power-consuming equipment in the cylinder is the filter, oxygen pump, heating rod and aquarium lamp. The power of the filter is about 50 W, which requires 36 kilowatt-hours of electricity a month. The power of the heating rod is about 100 W, which requires about 60 kilowatt-hours of electricity a month. In addition, the aquarium lamp consumes 12 kilowatt-hours of electricity, which consumes 100-200 kilowatt-hours of electricity a month.

Filter: The filter is an indispensable device in the fish tank. It can keep the water flowing. At the same time, when the water flows through the filter box, the impurities will be filtered out, so that the water becomes clear. According to the size of the fish tank, we should choose the appropriate flow of filtration to ensure that the water can circulate about 7-10 times per hour.

2. Oxygen pump: Not all fish tanks need an oxygen pump, but if you want to raise big fish or more fish, you need to turn on the oxygen pump all day. Once the symptoms of hypoxia occur, the health of fish will be seriously threatened, and even a large number of fish will die.

3. Heating rod: For tropical fish, the fish tank must be equipped with a heating rod to keep the temperature above 20 ℃, so that the fish can survive and grow healthily. Even eurythermic fish prefer higher water temperature, which will affect their appetite and cause them not to eat.
