There is an air pump in the tank to supply oxygen to the fish, which is from the bottom of the tank. The fish will die without oxygen, but the instructions say that the air pump can not run continuously for more than 12 hours. Will the fish die if they don't open oxygen? Or?.. How about the time of the air pump?.. Our fish is killing us!
Turn off the pump, and the fish will die.Because the air pump is used to increase oxygen content in the water supply. The water in the tank is closed water, and the oxygen content is limited. The fish continuously consume the oxygen in the water, which leads to the decrease of oxygen content in the water. If there is no air pump, feed oxygen, the fish will soon die because of lack of oxygen.Some fish I can breathe up the oxygen in the air, but the ability is limited, so long, the fish's resistance will decline, and finally to get sick and die.
Generally sleep about 2 hours before going to bed at nightGet up in the morning for a whileIn the summer, it's better to have cloudy days at the end of the day, and it's better to keep the fish open when it's cloudyOther fish floating head as long as there is no oxygen deficiency can not open
