How often should the filter be changed in the fish tank or aquarium

In fact, there is no fixed requirement for the time frequency of cleaning, about once a week to observe, if the filter cotton turns yellow, and the water quality is very poor, a little turbid, you can take out the filter cotton to clean it.

Generally, there will be 2 layers of filter cotton, an upper layer and a lower layer. The upper layer can be taken out for cleaning first, and after the cleaning is completed, it is placed in the lower layer and the lower layer is transferred to the upper layer. Wash in this way.

If it is not cleaned, the filter will be blocked, the water quality will deteriorate, and the living environment of the fish will be greatly deteriorated, resulting in death.

The frequency of changing the filter cotton in the fish tank is also related to the material of the filter cotton, if it is a synthetic fiber, it is about a month or so to change; Polyester foam.

If the material is changed, it will be changed every 3 months or so; If the biochemical cotton material is changed, it will be changed every 6 months or so. Or you can consider changing it every time you clean it, and when the filter cotton becomes thinner and thinner, or the quality of the filtered water gets worse and worse.

You can change it once in half a year, and if you don't have many fish, you can also change it once in a year, as follows:

The filter cotton in the filter box of the fish tank or aquarium can be changed once every six months.

If you don't have a lot of fish, you can also change it once a year.

If you raise a lot, you may have to change it once in about half a year, which mainly depends on the density of the filter cotton.

However, it is recommended that the filter cotton in the fish tank or aquarium should not be changed frequently; However, it can be replaced according to the situation, and the residue accumulated for too long will also affect the efficiency; It is recommended that you change the filter when it is really not in use (the filtration effect is obviously not good).

The reasons and precautions are as follows:

Filter cotton is the most dense place in the filter, and it is also the place where nitrifying bacteria multiply and grow most intensively.

Therefore, it is recommended that the filter cotton should be cleaned less, only half of it is cleaned each time, and the other half should be cleaned next time, and the clarified water of the original tank should be used when cleaning.

It is important not to think that the cleaner the filter cleaning, the better, and not to rub hard.

Cleaning filters should not be cleaned with detergents, let alone hot water, which will inhibit or collapse the nitrification system.

If it is very dirty, take a bucket of water that is replaced with the raw water in the fish tank, twist it casually by hand, and flush the dirt on the surface.

In addition, activated charcoal will change the pH value of the water and affect the growth of beneficial bacteria, so it is best not to use it unless the water has a peculiar smell.

Take a bucket of water that has been replaced with raw water in the fish tank, twist it casually by hand, and flush the dirt on the surface.

No need to raise fish! Leave it alone.

The fish tank filter cotton is cleaned once every half a month to a month.

The filter cotton is a place for cultivating nitrifying bacteria, so it can not be cleaned often, just clean it once every half a month to a month, and clean it with the raw water in the tank, not tap water. A part of the water in the fish tank should be taken, placed in a small basin, and the filter cotton should be put into it for rinsing, which can be properly rubbed without force, so that the impurities on the filter cotton float to the water surface, and then wring out the filter cotton.

Different materials have different service lifespans. Filter cotton made of synthetic fiber generally needs to be replaced once a month, filter cotton made of polyester foam can be used for 3 months, and the service life of biochemical cotton can reach 6 months.

What is the material of the fish tank filter?

1.Synthetic fiber filter

Under general conditions, synthetic fiber filter cotton is a full range of filter products that can fully replace non-woven fabrics and glass fiber covering coarse, medium and high efficiency, which is a new type of filter material and the main development direction of filter materials in the future. Compared with other filter materials of the same level, it has the advantages of low resistance, light weight, large capacity, environmental protection and incineration, and moderate quality.

2.Fiberglass filters

This kind of glass fiber is mainly made of various thicknesses, lengths of glass fibers through special processing technology. Glass fiber has the characteristics of stable performance, high temperature resistance, high efficiency, large capacity, and long service life.

3.Non-woven filter cotton

This kind of filter cotton has the technical characteristics of wide use, technical maturity and good stability, and is a typical filter material for primary and intermediate plate and bag filters. The production process is made by meltblowing, acupuncture, spunlace, spunbond and other processes through multiple processes, which has the advantages of stable quality, large dust holding capacity, strong moisture resistance, long service life, economy and durability compared with other filter materials of the same level.

The water should be changed once a month, and the filter cotton should not be changed often, wash it once a week, change it once every three months, and it is best to use the water in the fish tank for washing.

The water in the fish tank is generally the best, it is recommended to change it once every two weeks, and the filter cotton is also cleaned once every two weeks, which will be better, can achieve a higher cleaning effect, maintain the excellent water quality, and let the fish thrive.

In the process of fish farming, filter cotton can be used to purify the water quality. When using filter cotton, they inevitably get dirty, so they need to be cleaned regularly. The frequency of washing is mainly determined by the quality of the water.

If the water quality is good and the filter cotton is not easy to get dirty, then it can be cleaned once a month or even every 2-3 months.

Hello friends, under normal circumstances, the water in the fish tank is changed once a week, so it is better, and the filter cotton inside is changed once a month or so, which is better.

The water in the fish tank is usually filtered once a week, the amount of water is changed about 1 5-1 4, or twice a week, about 1 6 each time, depending on their own situation, as long as the water is clear and the fish is good, and the filter cotton depends on the density, feeding, variety, etc., some are only washed once a month and some are washed in two or three days. And there are those who are conditionally thrown away and replaced with another one.

In fact, the Arowana basically doesn't need to change the water, because while changing the water for the Arowana, the water you change is also likely to cause damage to the Arowana itself. Therefore, the Arowana family must first trap the water for the Arowana in the early stage of water change.

Points to note. When changing the water, you should pay attention to remember that you cannot change all the water at once, otherwise it will cause damage to the Arowana. At first, you can change the water with a small amount of new water, about one-eighth to one-sixth of the water in the whole tank, too much water change may cause the Arowana to adapt and other damage.

The amount of water can be changed according to the density of the fish in the fish tank, if the density is too high, and the fish raised is a more edible fish, then the water change needs to be more diligent, otherwise water pollution will also cause harm to the Arowana. In addition to avoiding direct contact with the Arowana itself when changing the water, it should also be noted that the water change should be maintained at a certain frequency, so as to provide a better living environment for the Arowana.

Arowana needs mildly acidic to neutral water quality for survival, and soft water for hardness. pH values between 3-12 DH values. The water temperature is 24-28 degrees Celsius. Nitrite content, as well as chlorine content, should preferably be zero.

No, you don't. The number of filter cleaning times is based on the load of the fish tank, if the density is large or large fish dominate, it is recommended to wash it for 3 days, if the density is small or small fish occupy the theme, it can be washed once a week. Rub the filter cotton with water a few times, and pass it with clean water.

Biochemical cotton can not be rubbed vigorously, as long as it is properly watered. Before the new filter cotton enters the filter, it is recommended to wash it with the original tank water. If the filter cotton is used for physical filtration, it will be washed when it is dirty, as for the time, it has to be determined according to the amount of food you feed and the amount of fish raised, and you can wash it when the dirt is attached too much, but don't wash it too cleanly, and it is best to wash it with the original tank water when the fish tank is changed.

How to wash the filter cotton in the fish tank? Fish farmers have a knack.

<>It's best to change it once a month and clean it up regularly every other week. However, if it is a polyester foam material, the filter cotton can be replaced once every 3 months. Since the filter cotton is a place for nitrifying bacteria, it is not possible to clean the hood frequently, and it is generally best to clean it once a week.

When cleaning the filter cotton, you should not use tap water directly, but use the water in the fish tank. In the process of cleaning, if you find that the thickness of the filter cotton becomes thinner and thinner, it means that its performance of filtering water has deteriorated, and then you can consider changing the filter cotton.

It is most appropriate to change the filter in the fish tank once a month. In the case of polyester foam filters, they can be replaced every 3 months.

Although the filter does not need to be changed frequently, the keeper needs to wash it once a week to avoid too much impurities on it and the filtration effect will deteriorate.

When cleaning the filter cotton, it is best to use the water in the fish tank, not tap water, to avoid chlorine residue, which will affect the normal growth of fish.

Most fish tanks will have 2 layers of filter cotton, one is close to the water outlet, and the other is placed on top of the other filter media, which can play a good isolation role. There are also some breeders who only use a layer of filter cotton, and if the water impact is large, a layer of filter cotton cannot guarantee that the impurities will be completely isolated. Depending on the shape of the filter cotton, the method used is also different.

The keeper can adjust the position of the filter according to the filtration method of the fish tank, so as to ensure that the effect of the filter cotton is better.

After using the filter cotton for a period of time, a large number of impurities and bacteria are attached to its surface, which needs to be cleaned frequently, so how often should the fish tank filter be changed? Take a look below.

01 The replacement time of the filter can be judged according to the material, if it is a synthetic fiber, it will take about a month at a time; polyester foam material for about 3 months at a time; Biochemical cotton material changes time for about 6 months.

02 Or we can observe whether it becomes thinner and thinner every time we wash it, or whether the quality of the filtered water deteriorates, and if so, we can consider replacing it.

03 How often can we also judge according to the density of the filter cotton, if the filter density is good, we can extend the replacement time. If the density of the filter is not good, it should be replaced in time to prevent the survival of the fish from being affected.

04 How often to replace the filter cotton is actually related to the number of fish we raise, if you don't have many fish we raise, we can choose to replace it once a year. If you raise a lot, it will take about half a year to replace it, of course, we usually need to pay attention to cleaning it.
