Whether fish need to be oxygenated all the time depends on the specific situation. Fish need oxygen for survival, and the ideal dissolved oxygen value is about 7 mg/L. When feeding, it is necessary to ensure that the dissolved oxygen value in the fish tank is between 3 and 5 mg/L. Therefore, when raising fish, oxygen pumps need to be added to the water to ensure the oxygen content in the water. But different fish and different situations have different needs for oxygen.
1. Oxygen consumption of fish: Parrot fish, Koi carp, map fish and other fish with high oxygen consumption. Therefore, when raising them, the oxygen pump needs to be turned on 24 hours a day. If it is a low oxygen consumption fish, it does not need oxygen throughout the day.
2. Breeding density: When the breeding density is very high, it is necessary to oxygenate all the time, because the fish will need a lot of oxygen at this time. It does not need to be oxygenated all the time when the breeding density is small.
3. Water plants: Water plants can release oxygen. Therefore, if there are aquatic plants in the fish tank, there is no need to give oxygen all day.
How long does the aeration pump run a day depends on the specific situation in the fish tank. If the density of the fish tank is too large, the fish are mainly high-consumption fish, or there are no aquatic plants in the fish tank, it is necessary to open the oxygen pump 24 hours a day.
