How often does a goldfish change its water?

Goldfish is a temperature-changing animal, relatively strong adaptability to water temperature, temperature changes with water temperature, in 0-39 degrees Celsius water temperature can survive. But goldfish can not adapt to drastic changes in water temperature, temperature rises sharply or drops more than 5 degrees Celsius, may endanger the life of goldfish, let's take a look at goldfish a few days for a water bar!

How often does a goldfish change its water?

Changing goldfish water requires regular, but not frequent, changes. Generally speaking, spring and summer season can be about 10 days to goldfish for water 1 time, and in winter, because the climate is lower water quality different decay, so the time for water change can be extended appropriately. Of course, this is when the water temperature drops below 4 degrees Celsius. Under normal circumstances, parents still need to change the water for goldfish normally.

What water do goldfish use?

1, tap water: tap water contains too much chlorine ions, can not be directly used for fish farming, generally use the cold drying method to put tap water in the open air ventilation, with the help of air circulation and sunlight irradiation, so that residual chlorine in the water volatilized, while increasing the dissolved oxygen in the water. The cool time is more than 24 hours in summer, more than 48 hours in spring and autumn, and longer in winter. In addition, chemical treatment can also be used, that is, the chlorine in the water is neutralized with soda, generally 2~3 grams per cubic meter of water or 5~6 grains per 10 liters of water.

Well water: Well water is groundwater, the water quality is hard, the water temperature is constant, and it needs to be exposed for more than 12 hours before use to balance the water temperature with the surface water temperature and increase the dissolved oxygen in the water.

3, river water: river water is natural water, water quality is soft but turbid, before use in the reservoir purification precipitation or filtration after use, which contains a lot of natural bait, can make the color of ornamental fish more natural bright.

How to change goldfish water

1, general water change: under normal circumstances, as long as the bottom of the fish tank dirt together with the old water, gently suck 1/10~1/5 with a hose, remove the surface dust and floating feces, and then slowly inject isothermal new water along the tank wall to keep the water clean, this water change method is not easy to hurt the fish body, the method is simple, most suitable for family fish tank applications.

Partial water change: Partial water change is mainly carried out in two cases.

① In the hot summer and early autumn, the fish tank feed water for a few days, and the water color turned green very fast, the water quality is still clean, in order to prevent goldfish hot tail, so you can put the goldfish in the tank all out, and then put the water in the tank into a spiral rotation, to be static for a moment, the center of the tank dirt and old water with a rubber tube to suck 1/3~1/2, and then inject isothermal, the same amount of new water, and then put the goldfish in.

② Another situation is that the water in the tank has only been changed for a few days, and the water color is still good. However, in the case of excessive feeding on the same day and floating head, the method of changing water is the same as that mentioned above.

3, thorough water change: thorough water change is often combined with turning the tank, selecting young fish or adult fish at the same time a water change method, often due to serious deterioration of water quality or moss is too long, fish too dense cases only adopted.

① In the absence of a free pool, we had to put all goldfish into the adjacent pool for temporary cultivation, and add oxygenator in the basin or cage. After washing thoroughly, re-inject isothermal new water, let stand for a moment until the water temperature is equal, and then fish into the original tank.

If there is a free pool, as long as all goldfish are caught in the basin and treated separately, this water change method should pay special attention to the water temperature, it is best to choose a sunny morning before 9 o 'clock, but this method is generally only applicable to adult fish or larger juvenile fish. Before completely changing the water, fill the spare tank with water, and then fish directly into the spare tank. This way, the water temperature changes little, and the fish are easy to adapt. This method of changing water in spring and autumn is generally carried out once every half month or so. Summer water temperature is as high as 28℃ above, in the case of water color is very easy to thick color, water quality is very easy to turbidity, 4~7 days should be thoroughly changed water 1 time. In winter, the water temperature drops to about 4 ° C, and no special circumstances generally do not change all the water.

In addition, goldfish breeders also have a breeding method called "green water", which controls the amount of phytoplankton and algae in the tank and keeps the water a little transparent green tea color. By eating phytoplankton in the water, goldfish can become more colorful, and at the same time, it can alleviate the drastic change of water quality when changing water. However, if there is no proper management, phytoplankton overgrowth makes the color of green water too thick, but it is easy to cause goldfish disease.
