Koi need oxygen. The growth environment of Koi needs enough oxygen, which can keep the cells of the fish permeable, enhance the vitality of Koi, and accelerate the growth of the fish. If there are fewer koi in the big tank, the dissolved oxygen in the water can meet the oxygen needs of the fish, but sometimes it can not meet the oxygen needs of nitrifying bacteria. The nitrification system is particularly important for filtration and water quality. Therefore, it is necessary to provide sufficient oxygen for nitrifying bacteria so that they can multiply in large numbers and maintain the balance of the nitrification system. If the fish owner feeds the fish too much and does not change the water in the tank for a long time, the requirement for filtration is very high. To sum up, Koi must be oxygenated.
Koi usually have a large amount of activity and absorb more oxygen, so it is necessary to install an oxygen pump. When the water quality is better and there are fewer fish in the tank, the aeration pump can be opened less. When the space of the fish pond or the fish tank is large and the water temperature is not high, the fish will not have a floating head condition, and the oxygenation pump can not be opened in this case. Otherwise, it needs to be opened for a long time.
