The editor has had such a situation before. I kept a tank of tropical fish, and they were all alive, but when the weather cooled down, the fish in the fish tank died one by one. At this time, the editor learned that the original tropical fish It is not resistant to cold and must have heating equipment.
The water temperature of most tropical fish should be 20-24 ℃. The water tank can be placed in the room facing the sun, and it can also be controlled by stove, kang, heating and electric heater. The electric heater is best equipped with a constant temperature device. When putting in and taking out, the power must be cut off first. At the same time, it is necessary to adjust the dissolved oxygen content in the water. Manually controlling the water temperature mainly uses heating measures such as stoves, kangs, and heating for heating. In recent years, the number of electric heating appliances in the market has been increasing, which is a better heating method. Most products have automatic temperature control functions, which should be preferred. such products.
In addition to aquariums and water quality filters, tropical fish rearing equipment also includes water quality circulating filtration equipment, heating equipment, oxygenation equipment, lighting equipment, and water pumping equipment. For a single aquarium, small circulating filter pumps, 100-200W heating pipes, single- and double-hole air pumps, fluorescent lamps, and small submersible pumps can be used. In addition, oxygenation equipment is also required. The oxygenation equipment for tropical fish includes single-hole air pump, double-hole air pump, four-hole air pump and turbo oxygenator. For a single aquarium, a single-hole air pump is optional. For multiple aquariums, a two-hole or four-hole air pump is available. Single-hole, double-hole or four-hole air pumps are all made of plastic materials, and they use the movement of rubber stoppers to complete the oxygen flushing work in the water. After a long time of use, the rubber stopper will be cracked or aged, and it should be replaced in time.
The most important thing in raising tropical fish is to control the water temperature. In summer, whether the heater is turned on or off has little effect, but once there is a cooling situation, the heater must be turned on, otherwise the tropical fish may freeze to death.
