? When conditions permit, it is best to oxygenate the fish tank, which can help goldfish grow healthier. When opening the tank, oxygen can help the fish tank to establish a nitrification system. Nitrifying bacteria are aerobic bacteria. Oxygen can make them multiply rapidly. The establishment of nitrification system can make goldfish survive better. When the goldfish is ill, oxygenation can increase the dissolved oxygen in the water, promote the metabolism of the goldfish, and indirectly help the goldfish recover. Oxygen can also help maintain water quality and reduce the number of water changes, which can also reduce the damage to goldfish caused by water changes.
Although goldfish need to be oxygenated, they don't need to be oxygenated 24 hours a day. Usually, under normal circumstances, the time of oxygenation is controlled between 2-4 hours a day, because the air pressure is lower at night, and the dissolved oxygen in the water will be lower. The oxygenation time can be chosen in the evening. If there are aquatic plants in the fish tank, it is also best to oxygenate for 1-2 hours in the evening. At night, aquatic plants will not only not produce oxygen, but also consume a lot of oxygen. In continuous cloudy days or summer, the oxygenation time can be extended to 4-6 hours.
