How often does the water in the open-air fish pond change?

Generally, it is more appropriate to change the water once every 10- 15 days. Usually pay attention to whether the water source is polluted. If there is pollution, water should be changed in time, and fish should be changed in time and disinfected once.

You can buy automatic water changing equipment to install. Press this button when you need to change the water. Otherwise, the water will be changed manually. In summer, the animal manure at the bottom of the fish pond should be cleaned once a day, and then new water should be injected to keep the water quality clean at all times.

In hot weather or early autumn, if the water in the fish pond turns green quickly, try to change the water. First, take the fish out of the fish pond, then suck out the dirty things in the middle of the pond with a rubber tube, slowly inject the isothermal new water, and finally put the fish into the pond.

If there are many fish, it is recommended to change the water frequently. When the moss grows faster in the fish pond, it is necessary to change the water frequently to ensure the survival rate of the fish. Generally, when the fish often come up and breathe heavily, it means that the oxygen in the fish pond is not enough for the fish to breathe, so it is necessary to change the water in time.

It is very hot in summer in dog days. Change the water once every 5-7 days, once every half a month in spring and autumn, and generally do not change the water in winter without special circumstances.
