Prepare a fresh water pipe, cover both ends of the water pipe tightly, release your hands, drain the aquarium water, remove the water pipe and filter the dirt.
1. First prepare a fresh water pipe (soft!) that is twice the height of the aquarium and place it under the faucet to fill the pipe with water.
2. Cover both ends of the water pipe tightly with your fingers, extend one end into the aquarium, and place the other end outside the aquarium.
3. The end outside the aquarium is lower than the end inside the aquarium.
4. Prepare a sink in advance and line it with a clean white cloth.
5. At this time, release both hands at the same time and the water in the aquarium will be pumped out.
6. Continue pumping until there is no more water.
7. Remove the water pipe timely, and the flowing water will be filtered through a cloth pto filter the dirt, and the water reaching the basin will be very clean.
8. Pour it back into the tank. Pour slowly to add some oxygen.
Detailed information:
Water used for fish farming should be changed regularly, not just whenever you want. And this regular water change is not a mechanical water change, but is carried out in a planned manner depending on the condition of the fish. For example, in summer, the temperature is high, the water quality is easily deteriorated, the algae in the water breeds easily, and the oxygen in the water is easily depleted, the frequency of water changes should therefore be more frequent. . In winter, water quality does not deteriorate so easily, so the frequency of water changes can be relatively slow.
Generally speaking, the water should be changed twice a weeke in summer and once a week in winter. However, this statement is for reference only. The specific frequency of water changes in the aquarium should be determined according to the actual situation if you raise a lot of fish and the filtration equipment and oxygenation equipment are not very good or even poor. do not exist, then the water must be changed. The frequency of water changes should be increased accordingly, and conversely, the frequency of water changes can be slowed down.
Don't be too lazy to change the water, especially if you see that the water for fish farming is relatively cloudy, with a lot of algae growing, and even ornamental fish need to float on the water. to breathe, then you can't even think about changing the water. If you don't change it, you will have to pay the price in fish lives.
