The filter in the fish tank can inject air into the tank, thus playing the effect of oxygenation. If there are not many cultured fish and the density of culture is not large, this kind of oxygenation can completely satisfy the growth of fish. If the breeding density is relatively large, oxygenation by filter is a drop in the bucket, at this time, the need for oxygenation pump this special oxygenation equipment.
1. Open the tank to use oxygen: The first step in fish farming is to open the tank. It is not just to buy a new fish tank to raise fish, but to provide a better growing environment by opening the tank. In this process, we need to establish a nitrification system, so we need to pour nitrifying bacteria, which is an aerobic bacteria, in order to make it grow and reproduce rapidly, we need to oxygenate.
2. Daily oxygen: In the process of raising fish, oxygen is also needed every day. Generally, the time of oxygen is determined according to the type of fish. If you raise goldfish or koi, the demand for oxygen is greater, so oxygen should be used all day, or oxygen can be used during the day and stopped at night. And tropical fish, oxygen 2-4 hours a day is enough, but in summer and rainy days need to oxygen 4-6 hours, if there are aquatic plants, you can oxygen 1-2 hours in the evening.
3, sick oxygen: If the fish is sick, also need to give it oxygen. On the one hand, oxygen can promote the metabolism of fish, which is helpful for the recovery of disease. On the other hand, because the drug will reduce the dissolved oxygen in the water, timely oxygen can be effectively supplemented to avoid suffocation and death of fish.
