How to change the water in a small fish tank, how to change the water in a small fish tank

Such a small fish tank is not worth installing a filtration device, you can dry some more water, and change the water every few days, anyway, there is not much water, and the operation is very convenient.

Even if the small tank is added with filtration equipment, it will not work, and the water quality will soon become rotten, so you can add an aeration pump to reserve more water Basically, you have to change the water once every 2-3 days.

There are miniature filters that are sold in the flower and bird market! Something to consider!

Fish and water, only when the water is raised can you raise good fish without worry, today I will talk about the precautions for changing the water!

Before changing the water in the fish tank, first prepare new water, put the water in the sunny place to dry for a period of time, you can pump out part of the old water in the fish tank, and you can inject new water after pumping, be sure to pour it slowly from the tank wall, do not change the water violently.

Whether it is the bottom filter fish tank or the upper filter fish tank, the back filter fish tank or the filter barrel filtration, it is recommended to turn off the water pump first, and after the water level is still, use the fish tank brush to wipe off the feces, food residues and algae attached to the bottom of the fish tank, at this time the water level in the tank is basically full, and if the fish tank brush is long enough, it can wipe off most of the algae and feces and other garbage that are left dust. After the undestroyed potatoes are generally wiped off, the garbage will slowly scatter and settle at the bottom of the fish tank after 10 minutes, and can be easily pumped out with a water change pipe.

Maintenance of algae in fish tanks

Cultivated algae need to provide clean water quality, change the water regularly, and the temperature is generally controlled at 10 degrees Celsius. Supplement the light, and if the natural light is not up to the requirements, place a small lamp. The easiest way is to find a stone with green algae growing on it and put it in the fish tank, so that some of the green algae spores can multiply quickly directly in the water body.

Be careful that if you cut stones with green algae in the field, wash them simply. Put it in clean water at home for a day or two to make sure there is no problem, and then put it in the fish tank to avoid bringing some pathogenic bacteria.

The method of changing the water in the fish tank is divided into the following four steps:

1.Turn off the water pump and clean the fish tank. Whether it is a bottom filter fish tank or an upper filter fish tank, a back filter fish tank or a filter bucket filter, it is recommended to turn off the water pump first, and use a fish tank brush to wipe off the feces, food residues and algae attached to the bottom of the fish tank with a fish tank brush when changing the water.

At this time, the water level in the tank is basically full, and if the fish tank brush is long enough, it can wipe off most of the defeated algae and feces and other garbage.

2.The fish tank is buried in silver and hidden water, and the filter cotton is washed. Take a clean basin or bucket, put the filter cotton in the filter tank (usually the magic carpet white cotton and other physical interception cotton in the filter tank responsible for intercepting feces) into it, and pump water out of the fish tank for cleaning.

In the vast majority of cases, the water in the fish tank is well suited to cleaning the filter cotton, which is not just a matter of saving water.

3.According to the actual situation, determine the amount of water exchange. The way of drainage from the fish tank is U-shaped pipe natural siphon, water pump connected to hose pumping, master tank forced discharge and other ways to pump water, no matter which drainage method is used, the amount of water exchange must be determined.

4.Adjust the temperature of the trapped water and slowly add water against the wall of the fish tank.

How to determine the amount of water change in a fish tank?

In the daily water change operation, it is generally 1 3-1 4 water exchange.

If the fish is in good condition, it can be changed more, and vice versa. Fish like old water, change less, and vice versa. After the drug is applied, in order to dilute the drug residue, it can be replaced. In summer, when the water temperature is high, the fish eat more and can change more, on the contrary, in winter, when the water temperature is low, the fish eat less and can be changed less.

Change the water in the fish tank, pay attention to the new water for two or three days, do not pour it directly into the fish tank, and pay attention to the temperature difference between the new water and the old water needs to be controlled within 3 degrees, only one-third of the new water is changed each time, and the water is slowly injected into the hole along the tank wall when pouring water. Also, be careful to disinfect the fish tank and filter.

Fish Tank Water Change MattersWhen changing the tap water in the fish tank, first use the basin to catch the water and dry it quietly for two or three days, and then pour it into the fish tank. If the temperature difference between the new water and the old water is large, the fish will be very uncomfortable, affecting the spirit and appetite, and the temperature difference needs to be controlled at about 3 degrees.

Be careful not to flush the fish directly with water, take out the old water first, and then slowly inject new water along the tank wall. At the same time, don't change all at a time, only change 1 3 new water, so that the fish can adapt to the new water environment better and faster.

When changing the water, you should also clean the fish tank and filter by the way. Dirt will also accumulate in the cylinder wall, cylinder bottom, and filter box, so it needs to be disinfected and sterilized.

Look at the temperature difference, the time of water change, and the speed of water change.

It is best to change on a sunny day. The time is usually in the morning.

The advantage of changing in the morning is that the temperature difference, and the irradiation time after the change, it is easy to create a new environment. In the afternoon, the temperature difference is relatively large.

However, on dog days, changing in the afternoon has the advantage of adjusting the temperature and reducing the "stuffy tank".

It is important not to change and fish at noon, especially in the green, and it is even more unsuitable to change and fish at noon, otherwise it is very easy to get sick.

The reason is: in the middle and upper layers of the hot layer temperature is relatively low, the bottom temperature is low, lying at the bottom of the tank can avoid the strong exposure and avoid the bad environment of less oxygen, if you change or fish at this time, it is easy to cause internal injuries and disease.

Goldfish (scientific name: carassius auratus), a carp of the family Crucian carp, also known as golden crucian carp, is an ornamental fish that evolved from crucian carp. Goldfish is divided into four strains: culture, grass, dragon and egg, which originated in China and is an ornamental fish with Chinese characteristics, and is now distributed in all countries of the world.

Its body is beautiful, there are many varieties, its body color has red, yellow, blue, purple, black, white, two-color, three-color, five-color color, etc., its body shape has lion head, high head, blister, dragon eye, pom-pom, pearl scales, butterfly tail, tiger head and so on.

Goldfish in the wild state have a greenish-brown or gray body, but there are various variations of goldfish, such as black, flower color, gold, white, silver-white, and three-tailed, dragon's eye, or no dorsal fin. Centuries of selecting and cultivating such abnormal individuals have produced more than 125 species of goldfish.

The correct way to change the water in the fish tank:1. The tools that need to be prepared for water change include heating rods, thermometers, and siphons;

2. Expose the water to be added to the fish tank to the sun, so as to remove chlorine and harmful substances in the water;

3. After exposure, heat the water to the same temperature as the water in the fish tank, and keep it warm;

4. After the water is treated, use the siphon to pump out the amount of water to be replaced in the fish tank, and then take the same amount of treated water and add it to the water tank.

Precautions for changing the water in the fish tank:Generally speaking, the amount of each water change is one-fifth to one-tenth of the original water volume of the fish tank, and the water change cycle needs to be adjusted according to the density of the fish. If the density of the fish is relatively low, you can change it every two weeks.

The fish tank should reduce the concentration of harmful substances by changing the water regularly, which can keep the water quality clear and stable, and the long-term stable water change can avoid the appearance of large areas of algae in the tank, and reduce the possibility of turbid green water quality and fish diseases.

Four benefits of changing the water in a fish tank:

First: In order to ensure the quality of the water quality of the fish tank.

Second: This can increase the amount of dissolved oxygen and nutrients in the water in the fish tank.

Third: Prevent the increase of harmful substances and germs in the water body.

Fourth: Promote the effective work of the filtration system of the fish tank.
