If the fish raised are not large and the number is not large, it is also possible to raise fish without using an oxygen machine, but if the breeding density is relatively high, it is best to use oxygenation equipment to give oxygen regularly.Usually the bigger the fish is, the higher the dissolved oxygen requirement is, and the more oxygen it consumes, so it needs to supplement oxygen, and the smaller the fish consumes less, so it does not need oxygen.There are also some fish with auxiliary respiratory organs, when the dissolved oxygen in the water is low, they can breathe in the air, so there is no problem without oxygen machine.
1. Daily: If you are raising large fish, you should oxygenate every day, but you don't need to keep the oxygen pump on all the time. It is enough to keep the oxygen pump on for 2-4 hours a day. If it is summer, the rising temperature will lead to a decrease in dissolved oxygen, so you need to keep it on for an additional 2 hours.If there are water plants in the tank, it will be opened for an additional hour in the evening.
2. Open the tank: The tank needs to be opened for the first time for fish farming. When the tank is opened, a nitrification system should be established. As nitrifying bacteria are aerobic bacteria, they also need to be oxygenated to promote their growth and reproduction. During this period, the lights should be turned off, and the light will also have an inhibitory effect on them.
3. Sick: After the fish is sick, due to the increase in the number of bacteria in the water, the consumption of oxygen will also increase. In order to ensure the breathing of the fish, proper oxygen is also needed.And some drugs will consume oxygen when they enter the water, which can be effectively supplemented by oxygen.
