The fish tank filters white cotton, and the filter material of the fish tank should be cleaned frequ

If you are biochemical filtration, white cotton can not be washed often, generally you can check once a month, the purpose of the inspection is to see if there are food residues that can not be decomposed by digestive bacteria, such as barley worm shells and the like, you can manually scoop it up, filter white cotton is the most vigorous place for nitrifying bacteria because there is more food, and so on! The back end of the filter tank is the weakest place of nitrifying bacteria, so it is recommended that the white cotton is not blocked and does not need to be cleaned, you can pay attention to the fish shop or a friend's fish tank (biochemically filtered) The top layer of white cotton is black and dirty, and the water is very clear, it is recommended that you do not need to wash the white cotton often, the water in the fish tank should be replaced regularly, such as 4 parts a week 1, you can judge the water change according to your fish tank capacity, fish density, and pollution situation, there is no formula for water change.

Wash it once every month or so, but be careful not to wash it too clean, because there are nitrifying bacteria on it.

Generally about 1 month, you can only wash one side or only a little, otherwise you should retain part of the nitrifying bacteria, remember not to be too clean, it is best to wash with the original tank water, it is the most perfect.

Depending on the situation, it is generally washed once a month.

How to choose a fish tank filter?

This depends on how dirty your fish tank is... You just look at when the water spills out of the filter box, it means that your filter cotton is dirty and needs to be cleaned.

The filter media does not need to be cleaned as often.

The filter material in the fish tank is mainly divided into physical filter media and biochemical filter filter media, which are generally these two.

To put it bluntly, physical filtration is to precipitate the debris and garbage in the tank on the filter cotton. Now there are magic carpets, magic bags, filter blankets and so on, the reason is the same. As long as you can keep the debris in the water out, you're fine.

The most dirty part of this part of the filter material is the top layer, there is no time limit, and it can be washed when it is dirty (as long as the water permeability is normal, there is no need to wash.) ）。Washing diligently reduces the service life, and it is good to wash it once in 10 days!

The effect of biochemical filtration is to cultivate the nitrifying bacteria in the water and generate a more beneficial nitrification system in the fish tank. Although there are many types, most of them are still mainly ceramic rings, bacterial houses, biochemical balls, biochemical cotton, etc., supplemented by others.

In the case of good physical filtration, the filter material of biochemical filtration basically does not need to be cleaned in a large area, and it can be cleaned once every six months or a year. In order not to wipe out all your nitrifying bacteria at once, of course, it is necessary to clean it in batches, and there is really no specific standard for this, so it is cleaned up in three or four times.

Upper filtration: Because the space is relatively small, the filter material (ceramic rings) is placed at the bottom, the second layer of biochemical filter cotton, the top layer of physical filter cotton, and the top layer of physical filter cotton is simple and clear when changing the water.

Sail Travel Trickle Box: This kind of space is relatively large, the original intention of the design is also for large-area filtration, but more space is used to stack filter materials, only a box or half a box is used to put filter cotton, the same principle, biochemical filter cotton in the middle, the top layer of physical filter cotton, easy to clean.

Filter cartridge: its principle is a bit similar to the trickle box, the difference is that the speed of water is faster, the amount of water is larger, the drip is slowly seeping down, the water flow is relatively gentle, and the impact of the water flow of the filter cartridge is relatively large. So the principle of placement is the same as that of a drip box.

Bottom filtration: This is the most powerful filtration effect, several subdivided cylinders are used to install filter materials, the order of filter cotton and filter material is like this, the water inlet is the closest, put physical filter cotton, followed by biochemical filter cotton, and finally filter material. Because the water outlet is the dirtiest, it is physically filtered out first, which is also convenient for cleaning, and then some of the substances in the water are just processed by the filter material, that is, through nitrifying bacteria.

The kind that has been done is not very good for the general stuffy grip, so I suggest that you improve it. Buy a finished product and filter it, or scrape this version off with a blade bit by bit. Glue two pieces of glass and snap them into a filter basket on the top of the cylinder.

are all good choices. And then that's it.

You said that the kind of upper filter of Ant Shuqing, the kind with partitions, there are three in my house. However, each one of them was thrown away because of the overflow problem at the end. Finally, it is the filter basket that is chosen. The most affordable.

1. The first thing is worn out and filtered, and then the biological filtration.

2. Physical system filtration bai generally uses filter cotton (acrylic fiber) to block residual bait, fish feces, etc.

3. Biological filtration is the oxidation of ammonia, nitrite and other toxic components produced by humus bacteria after decomposing organic matter into basically non-toxic nitrate by nitrifying bacteria.

4. In a few cases (feeding corals, anemones, etc.), it is necessary to use denitrifying bacteria to reduce the nitrogen in nitrate to nitrogen.

5. The coral sand you said is a porous filter material, which should be used as a biological filter material 6. The main component of coral sand is calcium carbonate, which will make the water quality hard, and it is best not to use it for some tropical fish species that do not like hard water (such as lamp fish native to South America).

1. Hair brush: Collect some hairs and put them in a simple strainer with mountain bends as part of the filter cotton. This method can reduce the damage to animal hair while providing adequate filtration.

2. Sponge: Placing some sponge in the filter can provide a stronger filtration effect than the filter cotton. These sponges can absorb water, which can reduce the amount of impurities in the water in some cases.

3. Paper filter material: Put some thick and stuffy paper filter material in the filter, which can provide a filtration effect similar to that of filter cotton. These paper materials can trap impurities in the water and prevent them from entering the fish's trough.

<> fish tank filter cotton is generally placed on the top layer of the filter box. Filter cotton is generally padded with two layers, the first layer is physical filter cotton, and the second layer is biochemical cotton. If you usually wash the filter cotton, you can't scrub it, you need to soak it in the original tank water, and then throw out the dirt, or rinse it with a water gun.

The reason why it can't be scrubbed is because it can be easily washed out, and once the structure is damaged, it can't filter the fine dirt.

Aquarium knowledge, the correct use of fish tank filter cotton, have you used it correctly.

The upper layer of the first consideration groove must have placed several layers of overconsideration surfaces. This makes it easy to take out and clean. The culture cycle of nitrifying bacteria is very slow, and the attachment should not be disturbed frequently.

So it basically doesn't move in the later stage. The environment in which nitrifying bacteria grow is a porous material, protected from light. If these two conditions are met, nitrifying bacteria can grow on their own.

I've tossed all kinds of biochemical cotton, glass changers, magnetic rings, and so on before. Later, I saw the Arowana farmed in the fish market, and the filter material was very simple (of course, the role of the filter material was not excluded), and the effect was also very good, and the water quality was transparent. Now I put 6 layers of filter cotton on the upper layer of the first grid, which is mainly used to worry about large objects in the water and facilitate cleaning.
