all the time? If the density of goldfish in the fish tank is too high and the oxygen consumption is very fast, then it is necessary to oxygenate the fish tank all the time, otherwise the goldfish will die easily because of lack of oxygen. However, when raising goldfish normally, as long as the density of goldfish in the fish tank is reasonable, then the goldfish will not always lack oxygen, there is no need to give oxygen to the goldfish all the time. Goldfish generally consume more oxygen when eating, so they can oxygenate the fish tank during this period. Then the dissolved oxygen in the fish tank will be relatively low in rainy days and in the early morning every day. At this time, it is also necessary to oxygenate the fish tank. Basically, giving oxygen to goldfish for a few hours every day can meet the needs of goldfish.
Under normal circumstances, has been playing oxygen to the goldfish, for the goldfish is no harm. But in the daily feeding process, goldfish are not always anoxic, after the dissolved oxygen in the water reaches saturation, it is useless to continue to oxygenate. So although giving oxygen to goldfish all the time is not harmful to goldfish, it will not only waste resources, but also greatly increase the cost of raising goldfish.
