if the water circulation of the fish tank is slow? If the water circulation of the fish tank is slow, the power of the pump can be increased. If the pump can not be adjusted, it can only be replaced with a new one. In addition, if the water circulation slows down because it is used for too long, it may be caused by the blockage of the filter cotton. At this time, just take out the filter cotton and clean it. It should be noted that the filter cotton should be washed with the original tank water, not with new water, otherwise the nitrification system in the tank will be destroyed.
of water circulation? 1. Help with filtration: The primary benefit of water circulation is to help with filtration. If the water body is static, the filtration can not be completed at all. Only when the water flows, the filter material in the filter box can filter out the impurities in the tank and keep the water body clean and sanitary, which is of great help to the maintenance of water quality.
2. Increase dissolved oxygen: When the water flows, the contact between water and air increases, which can also increase the dissolved oxygen. It should be noted that for fish tanks with low feeding density or small fish, the increase of dissolved oxygen is meaningful, while the increase of oxygen for large fish is insignificant, and oxygen pumps are still needed to oxygenate them.
3. Beneficial bacteria: When the water circulates, nitrifying bacteria can also maintain a certain degree of activity. Once the water is still, they will die in large numbers, thus destroying the ecological cycle in the tank and threatening the health of fish.
