1 2 meters long 0 4 wide 0 5 high Sensen upper filter fish tank how to choose the filter barrel

The key to raising good fish is filtration, and filtration is mainly to filter fish feces, and the toxins in the water are produced by fish feces. At present, the general aquarium filtration system is mainly upper filtration, drip flow, bottom filtration, filter barrel, side filtration, and back filtration, which are different in form, but essentially the same, all of which are filtration systems for cultivating nitrifying bacteria outside the tank. That is to say, the fish feces must be extracted into those filters before nitrification, and the ammonia in the fish feces can be removed.

Fish do not have long legs will not automatically go to the water inlet to be pumped out, need to pass through the water flow in the tank to pump most of the fish into the filter body, usually need to cooperate with the use of wave pumps, when the wave pump works, the fish will float the whole fish tank, and it takes time to filter all these water bodies, during this time the fish will be partially dissolved in the water, polluting the water body to increase the ammonia content, and the fish will be prone to disease. Therefore, it is often necessary to use a straw to suck out the fish feces in time and change the water frequently to reduce the burden of filtration, which increases the difficulty and workload of maintenance. Yongqing Filtration understands that this system has the function of automatically cleaning up fish feces, which will help.

If you want to have a good effect, you can directly make a plan for yourself There are many professionals on the Internet, and it is very good to recommend that you learn, it is very simple. The most important thing is that it is effective, practical and cost-effective.

You can worry about it, and you need to buy an external filter barrel to fill it, and you will be told when you buy it.

Summary. Theoretically, you can use a 100-120 fish tank filter bucket to filter a 30-50 fish tank. However, it should be noted that the flow rate and filtration effect of the filter bucket need to be adjusted according to the size of the tank and the number of fish.

If the flow rate of the filter bucket is too large or the filtration effect is too strong, it may adversely affect the water quality in the fish tank and may even cause the death of the fish. Therefore, it is recommended that when you choose a filter bucket, you should choose a suitable filter bucket according to the size of your fish tank and the number of fish, and at the same time pay attention to adjusting the flow rate and filtration effect of the filter bucket to keep the water quality in the fish tank stable. If you're not sure how to choose and adjust your filter bucket, you can consult a fish professional or head to a pet store for help.

Can a 30-50 fish tank use a 100-120 fish tank filter bucket.

Fellow, I really didn't understand, I can be more specific.

Generally, the size and unit of measurement of the water body are calculated first.

Attack: liter (l). Then multiply the value of the water volume by 6 to obtain the hourly flow value of the filter barrel water pump, the unit of measurement: liter hour (l h). This value will be marked on the parameter description of the filter barrel.

Here you need to know the specific width and height of the fish tank, whether there is a bottom filter, and whether it is paved with sand and gravel. Suppose the size of your fish tank is 120*45*45 (unit cm), and the actual water body is about 200L, then you can choose a filter bucket of 1200L H. The power is about 25-30W.

120-1×2）×（45-1×2）×40=202960（ml）≈200（l）

1 2 is the thickness of the cylinder wall, and 40 is the actual height of the water body.

In addition, if the cylinder is relatively deep (e.g. 80 cm deep), the power of the filter drum can be increased slightly.

By the way, the general grass tank is more suitable for the use of filter barrels, if you are raising large fish, feces and food residues can easily block the filter barrels.

The first grid is placed with physical filtration, white cotton, black cotton, rattan cotton and the like, if it is dry and wet separation, put these above, put the filter material below, place the filter material in the second grid, and put the water pump in the third grid; If it is a four-bottom filter tank, in the same way, the two in the middle are the same as above.

The placement and attention of the filter material at the bottom of the fish tank

1. Filter the first step of the dry and wet separation box, and place as much filter cotton as possible.

2. Under the dry and wet separation box, the first grid is filtered, all the high-quality rattan cotton is put on, and two layers of white cotton are placed on the rattan cotton. Therefore, the size of the cotton should be slightly larger than the size of the filter grid, measure it when you buy it, and soak it in water before using the new one.

3. The second grid is all put in the bacteria house, (the second grid and the third grid of the 4 grid bottom filter are put in the bacteria house), the bacteria house is cost-effective, and it is the first choice for most aquarists to cultivate bacteria. However, there are two points to note: the first is to buy a bacterial house to buy a general **, don't buy a particularly cheap one, the quality is not guaranteed, and don't buy a particularly expensive one, the quality is good but the cost performance is not high, anyway, it is better to buy NO1 (statement:

There is no intention to advertise for NO1). The second is that the pH value of the current bacterial house is generally very high, so you should soak it in the water for three or five days before buying it, and change the water every day, so that the impact on the pH value of the water in the tank will be much smaller after use, please pay attention to it.

4. In addition to the submersible pump and heating rod, the last grid can put some Maifan stone (5 catties in a tank of one meter eight is very suitable, for your reference), Maifan stone can release a variety of trace elements required by Arowana, can live water, adsorb bacteria, two-way adjustment of pH value, etc., is a very ideal filter material, I am very respected. (Disclaimer: The role of Maifan Stone is scientifically certified, you can go to the encyclopedia to check, I have no intention of advertising Maifan Stone.)

Last but not least, regular and quantitative water changes and submersible pumps with the right flow rate are also very important to maintain good water quality!

It mainly depends on how many you have at the bottom filter tank: if it is three grids, the first grid is placed with physical filtration, white cotton, black cotton, rattan cotton and the like, if it is dry and wet separation, put these above, put the filter material below, place the filter material in the second, and put the water pump in the third grid; If it is a four-bottom filter tank, in the same way, the two in the middle are the same as above. The purpose is to put cotton and the like first according to the water inlet to the outlet, then put the filter material, and then put the pump!

The first trough is full of cotton, and the second trough is full of bacteria.

6-8 times will do. However, this traffic refers to the actual traffic, not the standard traffic of the bucket.

The flow rate marked by the filter barrel and water pump refers to the maximum flow rate at 0 head, but we rarely put the bucket on the same level of the fish tank in the actual use process, and most of them are placed in the bottom cabinet, so it is necessary to calculate the head loss. The formula is as follows:

Actual flow rate = (marked head - actual head) Marked head * Marked flow.

For example, a pump is marked with a head meter and a flow rate of 1000l h. Your pump is placed at a vertical distance of meters from the horizontal plane of the fish tank.

Actual flow = (

Actual flow = 556l h

We are not too small in the filter barrel, the larger the water filtration, the better.

Summary. There are several options for cylinders of this size.

1) Wall-mounted waterfall filter. The cost is low, but the filtration effect is very average next to a small piece of filter cotton, about 20;

2) Wall-mounted filter barrel. The filtration effect is much better than that of the waterfall, but ** has come up, more than 60;

I have a wide and tall fish tank, what kind of filter box should I use?

There are several options for this size tank: (1) Wall Mounted Waterfall Filter. The cost is low, but the filtration effect is very general next to a small piece of filter cotton, about 20 high; 2) Wall-mounted filter barrel. The filtration effect is much better than that of the waterfall, but ** has come up, more than 60;

Thank you. I have fish, the water is always bad, and the fish die, and I want to purify the water, but I don't understand this.

You can try the wall-mounted one.

Okay thank you.

You are welcome. How can red carp survive better?

It is generally not easy to breed at home. Normally, the female fish lays eggs at the same time as the male fertilizes the eggs. Eggs cannot be fertilized after a few minutes in the water.

This is because fish eggs have a mucous membrane when exposed to water. There should be no male fertilization when your female fish spawns, and it is not absolute. Now look at the fish eggs.

Look at the transparency of the eggs, if the transparency is high, the number of masks is defeated, and it proves that it has been fertilized. If it is white, it is opaque. The proof is a dead egg.

Remove the dead eggs. Otherwise, it will rot and pollute the water quality. If you have transparent eggs, congratulations, stop the pump, because it will pump the small fish out.

Use an air pump to administer oxygen 24 hours a day. Fish eggs require high culture.
