How often should the water be changed in the ecological fish tank, and the water should be changed e

The water should generally be changed once a week, each time the water is changed to the fish tank 1 5 to 1 3 is more appropriate, if you change more, the water quality will change, the fish and the plants in the tank can not stand it!

Generally speaking, laying sand and planting grass in the tank, opening the filter, and adding beneficial bacteria regularly have a great effect on purifying the water quality. However, although our aquarium can establish a good ecological filtration system, this ecological environment is still too small, and the density of fish is too large compared to natural waters, so the "ecological balance" is more likely to be destroyed. The transformation of water quality and water environment is mainly due to the deposition of fish feces and erbium residues, turbidity of water quality, oxygen consumption of organic matter, and the production of harmful hydrogen sulfide gases; or the algae are vigorous, and the photosynthesis of aquatic plants is affected; The physical and chemical properties of water change due to the evaporation of water or the increase of organic matter, etc.

If the aquarium is large and there are few fish to be raised, this transformation may be slower. If the aquarium is smaller, and there are more fish, and the conversion may be carried out more quickly if you are fed fish worms, artificial burgers, etc. A well-functioning filtration system is necessary, but changing the water is still the basic solution.

For bare tanks, it is best to use a siphon to suck out the dirt at the bottom of the tank every day in combination with a water change, and add an appropriate amount of fresh water. For the water plant tank, the water can be changed 1-2 times a week, and the special suction pipe can also be used to suck out part of the dirt in the sand, and the water exchange per week is about 1 3 of the total water volume. For different water quality conditions and different fish, the number of water changes and the amount of water changes should also be different.

If the fish density is large, the volume is small, and the water quality is easy to turbidize, it may need to be filtered day and night, and more water may be changed every day. If the betta fish has a small amount of activity and likes old water, it should reduce the number of water changes and the amount of water exchange. When changing the water, pay attention to the temperature difference of the water should be controlled within 4.

Fish that are sensitive to water temperature should control the temperature difference to a smaller range.

How often should the water in the fish tank be changed? The teacher explained two points and two musts, hoping to help everyone.

The small fish tank should change the water at least once every 3 days or so, when the ornamental fish in the small fish tank appear high-frequency bubbles, indicating that there is a lack of oxygen, and the water needs to be changed in time. Note that the new water needs to be exposed to the sun for about a day, and the temperature difference of the water should not be higher than 4 degrees during the water change process.

For ornamental fish raised at home, although the water in the tank is very clean, it is still necessary to change the water regularly, generally at least once every 3 days. Raising ornamental fish in winter can appropriately reduce the frequency of water exchange.

However, when the ornamental fish floats in the water and frequently spits bubbles, it means that there is a serious lack of oxygen in the water, and the water needs to be changed in time. The new water must also be exposed to the sun for about a day, or in the shade for about 3 days, before the water can be changed.

When changing the water in a small fish tank, do not directly replace all the water, and the temperature difference of the new water should not be higher than 4 degrees. In addition, when feeding the feed, it is necessary to feed a small amount many times, otherwise the ornamental fish are easy to be sustained to death, and they cannot be fed at night in the crack.

Generally, it should be changed once a week, and it is more appropriate to change the water to change the fish tank 1 5 to 1 3 each time, if you change more, the water quality will change, and the fish and the plants in the tank can not stand it. Generally speaking, it is said that laying sand and planting grass in the tank, opening the filter, and adding beneficial bacteria regularly have a great effect on purifying the water quality.

However, although our aquarium can establish a good ecological filtration system, this ecological environment is still too small, and the density of fish is too large compared to natural waters, so the "ecological balance" is more likely to be destroyed. The transformation of water quality and water environment is mainly due to the deposition of fish feces and erbium residues, the turbidity of water quality, the oxygen consumption of organic materials, and the production of harmful hydrogen sulfide gases. Or the algae are vigorous, the photosynthesis of aquatic plants is affected, the physical and chemical properties of water are changed due to the evaporation of water or the increase of organic matter, etc.

The water change time of the fish tank should be determined according to the situation, under normal circumstances, the water in the fish tank should be changed once a week. If it is during the change of seasons or the water quality is relatively poor, the water should be changed once every three or four days, and the amount of water to be replaced should be increased.

It should be noted that the more you change the water each time, you can change one-fifth of it, and the more diligent the water change, the less water you will change, so as to avoid large fluctuations in water quality and affect the health of the fish.

Points to note for changing the water in the fish tank:

1. Water exchange: Every time you change the water, you don't have to change all the water each time, only 1 5 1 3 water, so that the fish will adapt to the new water quality faster and there will be no discomfort.

2. Change the water temperature: pay attention to the water temperature when changing the water, and the temperature difference between the new water and the old water should not exceed 3, otherwise the fish will be uncomfortable, and the probability of getting sick will exceed 30%.

3. PH value: PH value changes greatly and also harms the fish a lot, before raising a certain kind of fish, you must know the water temperature and pH value, water hardness, etc., first adjust the water to a suitable environment for the survival of the fish, and then change the water will be better.

Fish eat and drink Lazar are in a fish tank, the space in the tank is limited, the water is also fixed, even if the filtration is good, the garbage generated by the fish in the tank is transformed into harmful substances continue to accumulate, and the toxins always exceed the standard one day, that is, the day of the fish's violent death. All these toxins can only be diluted by changing the water. Only by reducing the toxins can the fish not get sick or die in a bad state.

An eco-fish tank is a special type of fish tank with hydroponic plants, special lights, and a filtration system. The ecosystem in this tank is relatively complete, but that doesn't mean it doesn't need to be replaced. Regular water changes can avoid the loss of some trace elements in the ecological fish tank, and at the same time prevent the accumulation of nitrates.

In general, change the water at least once every two weeks. Each water change can replace one-fifth to one-third of the overall water volume, and not too much.

The ecological fish tank is a special fish tank with some hydroponic plants, special lights, and a filtration system, etc., which can form a miniature ecosystem. Some farmers will think that the ecological fish tank does not need to be replaced. In fact, this is not true, ecological fish tanks also need to change the water regularly, but compared with ordinary fish tanks, the number of water changes can be less, and the amount of water changes can also be less.

If the water is not changed for a long time, the trace elements will be lost, and nitrate will accumulate more, and in general, such an environment is not suitable for the growth of fish.

In general, it is necessary to change it at least once every two weeks. If you have more time, you can replace it once a week or so. You must not change it for a long time, let alone a whole year. When changing the water, it is necessary to control the amount of water exchange, and replace one-fifth of the overall water volume.

One, a quarter or a third is OK, not too much, otherwise the water quality will change significantly, which will make the fish and the plants in it unable to adapt.

If you use a normal fish tank to raise fish, you need to change the water slightly more frequently. Generally, it needs to be replaced every 5-7 days. In the summer when the temperature is relatively high, it generally needs to be changed once every 3-5 days.

However, in winter, it doesn't need to be so frequent, basically once every half a month. Since there is no ecosystem like an ecological fish tank in an ordinary fish tank, the step of changing the water will be relatively more important, and the water quality will be very poor if the water is not changed regularly.
