happens if there is too much oxygen in the fish tank? Too much oxygen in the fish tank is a good thing and has no effect on the fish. Although in the case of oxygen saturation, fish are prone to bubble disease, but generally the oxygen in the water will not be saturated, even if the oxygen pump is open for 24 hours, because the oxygen pump into the water is not pure oxygen, but air, the oxygen content of the air itself is not high, plus the part dissolved in water is very small, so it will not cause gas saturation in the water.
? 1. Daily oxygenation: The fish tank is usually oxygenated every day. According to the feeding density of the fish, you can choose to open the oxygenation pump 24 hours a day, or you can open it in stages, two hours a day in the morning and two hours in the afternoon. If it is summer or rainy weather, it is often necessary to extend the opening time of oxygen pump.
2. Oxygenation during illness: If the fish is sick, it is often necessary to oxygenate the fish tank. On the one hand, oxygenation can maintain water quality and slow down the deterioration of water body, which is helpful to the recovery of fish. On the other hand, medication for fish often consumes a certain amount of oxygen, so it needs to be supplemented with oxygen.
3. Open the tank for oxygenation: For the first fish culture, it is often necessary to open the tank for bacteria culture, and the bacteria culture is nitrifying bacteria. As an aerobic bacterium, its growth can not be separated from sufficient oxygen. Therefore, it is best to turn off the lamp and explode the oxygen for a period of time after pouring in the bacteria culture material, so as to establish the nitrification system as soon as possible.
