There are many reasons why the fish tank oxygen pump does not bubble. If it is determined that there is no problem with the oxygen pump, it is placed in the wrong position. Because the oxygen pump needs to pump gas into the water, which requires a certain amount of air pressure. If it is lower than the water, it may not be able to pump air. It may also cause water to flow back into the pump from the tank due to siphoning, resulting in damage to the oxygenation pump.
1. Power: The power of the oxygen pump is a very important issue, not the greater the power, the better. Fish tanks generally have filters, filters will produce water flow, if the power of the aeration pump is too large, it will change the direction of water flow, which will affect the filtering effect, resulting in water turbidity. Therefore, we must choose the right power of the oxygen pump, which is generally related to the size of the fish tank.
2, gas volume: Oxygen pump has a single hole or porous, no matter which one, when buying must check its gas volume. You can put the trachea into the water and check it to see if it can be adjusted effectively.
3. Sound: Because the oxygen pump is a motor, there is a little noise more or less, but try to choose a smaller noise, too loud sound will not only affect life, but also frighten the fish, leading to stress reaction, or even death.
