? Fish tanks with circulating pumps usually change water once every one to two weeks. Circulating pump can play a filtering effect, which is helpful to the maintenance of water quality, so it is not necessary to change water too frequently, but because the cycle of changing water is relatively long, so the amount of changing water should be a little larger, usually about one third of each time, so that the water quality can be maintained for a longer time. In addition, the novice must be sleepy before using.
of the fish tank circulating pump? 1. Help filtration: The main function of the circulating pump is to help filtration. It can make the water in the fish tank flow, on the one hand, it can make impurities gather, on the other hand, it can play a filtering role when it passes through the filter material. If the water can't flow, the effect of filtration will be greatly reduced, or even completely ineffective.
2. Promote activities: Fish live in the water, and the flow of water can also promote its swimming. Only when it keeps swimming can it not be washed away by the current. Because fish swim, its metabolism will be accelerated, and at the same time, it can promote digestion, which is very helpful to its health, and even reduce the possibility of disease.
3. Maintain water quality: Water circulation is also helpful to maintain water quality. As the saying goes, running water is not rotten, and the growth and reproduction of microorganisms will be limited to a certain extent. Moreover, flowing water is also helpful to nitrifying bacteria. If the water is still, the nitrification system is easy to collapse.
