responsibility, the fish tank often dead fish, explained has not opened the tank, the water quality has the big question, in view of this situation, the best way is to open the tank again. To open the tank, you need to disinfect it first. Potassium permanganate is usually used for disinfection. After filling the tank with water, you can pour in the medicine and soak it for 1 hour. After that, we need to raise water. To raise water, we should first trap the water, then pour in nitrifying bacteria and turn off the light to explode oxygen for a period of time. When the water is muddy and clear, it means that the water is well raised and the fish can be released.
in the fish tank 1. Stabilize the water quality: To prevent the occurrence of dead fish, the first thing to do is to stabilize the water quality. If the water quality deteriorates or fluctuates greatly, the fish will die. Therefore, the water should be changed every once in a while, and about a quarter of the water should be changed each time. Water should not be changed too frequently, nor too much at one time.
2. Control the water temperature: As a poikilothermic animal, fish have limited ability to adapt to temperature changes. The temperature difference in a day should not exceed 2 ℃, so that the fish will not die easily. In addition, if tropical fish are raised, the water temperature should be kept above 20 C. Heating rods can be used to control the temperature.
3. Disease prevention: Some fish diseases can also cause a large number of fish deaths. If you want to prevent them, you need to pay attention to changing water and controlling temperature at ordinary times. At the same time, anything put into the fish tank must be disinfected to ensure that harmful bacteria will not be brought in.
