the noise caused by oxygen pump resonance? There are two ways to eliminate the noise, one is to rely on shock absorption, the other is to rely on isolation. There are many ways to absorb shock, such as putting a cushion on the bottom of the oxygen pump, or suspending it so that it does not touch the ground, so that the noise will be reduced. Isolation is even simpler. Prepare a cardboard box slightly larger than the air pump and turn it upside down to isolate the sound.
the oxygen pump 1. Daily opening: It is better to keep the oxygen pump open all the time, so as to avoid the occurrence of hypoxia. If there are not many fish, it can also be opened at different times, four hours a day, two hours in the morning and two hours in the afternoon. If it is rainy weather, it is better to extend the opening time.
2. Cultivate bacteria: Fish farming needs water, and water farming needs bacteria. Many beneficial bacteria belong to aerobic bacteria, so they also need to be oxygenated. Usually in the first month of opening the jar, some raw materials for cultivating bacteria should be added every week, and then the lights should be turned off for a period of time, so as to accelerate growth and reproduction and establish a good ecological balance.
3. Sick: When the fish is sick, it also needs to be oxygenated with an oxygen pump. Because harmful bacteria in water tend to consume oxygen, if not oxygenated, the health of fish will be threatened. Moreover, sufficient oxygen can also ensure the metabolism of fish, which is conducive to the discharge of harmful substances and is helpful to their rehabilitation.
