Fish tank 1 tips for choosing submersible pump. How to choose submersible pump for fish tank?
The choice of fish tank pump is mainly influenced by three factors:
1, cylinder size: This is mainly the water volume of the whole cylinder, and the flow rate (L/H) of submersible pump generally circulates the whole cylinder water 7- 10 times per hour.
2. Filter bin size: because the larger the volume of the filter bin, the more filter materials can be added, the larger the filtering area of the filter materials and the larger the overall filtering area; At the same time, it also means that the large filter bin can bear more water flow.
3. Density of fish: The more fish you eat, the more excrement you produce, and more flow is needed to clean the water. At the same time, many small white fish friends found that feces could not be pumped out, often because of low pump power and insufficient pumping capacity.

3. How to choose a suitable submersible pump according to the size of your fish tank?
Choosing the right submersible pump depends on the right pump power. The factors to be considered in selecting submersible pump are: the size of fish tank, the form of filtration, the richness of filter material, the breeding density, the size of fish, the types of fish and so on. To put it simply, if the capacity of the fish tank is larger, the filter material is less and simpler, the culture density is higher, the fish is bigger, and the metabolism of the fish is faster, then the power of the submersible pump needs to be greater.
Configure the appropriate water pump according to the size of the fish tank. When medium-sized and large-sized fish are cultured in finished tanks filtered by ordinary top tanks, it is more suitable to configure a water pump with a capacity of about 25 watts per tank 100 liter of water. For example, if the fish tank is 1.2m long, 0.35m wide and 0.5m water level, then the water capacity of the fish tank is1.2 * 0.35 * 0.5 *1000 = 210 (l), so it can be considered to equip with two 25w or 45w. Or consider dividing it into two water outlets, one is to create flow directly in the cylinder, and the other is to introduce water into the top tank for filtration.
4. How to choose the aquarium pump that suits you?
1. What kind of filtering should I choose first?
(1) wall-mounted waterfall filter. The cost is low, but this kind of filter screen is generally small, and the filtering cotton on it is naturally small, and the filtering effect is naturally not strong. It is more common in fish tanks with a length less than 30CM, because there is often no better choice for small fish tanks;
(2) Wall-mounted filter barrel. The filtering effect is much better than that of waterfalls, but the price has come up, and the price of 40-60 cm cylinders is often appropriate;
(3) Small built-in filter. Generally, it has two functions of filtration and oxygenation, and its ability to pump fish manure is very poor. The only advantage is that it does not occupy the external space of the fish tank. In addition, some finished fish tanks will have this filtration;
(4) Independent filter barrel. The filtering effect is very good. Generally, it is easier to buy a suitable type of filter barrel for a cylinder with a length of more than 40CM. In addition, the straw bucket containing CO2 must use the filter bucket, otherwise CO2 will easily escape; In addition, it should be noted that the advantage of the filter barrel is that the filtration is very fine, but if the filter barrel is used to raise fish that can eat and pull, the system must be large (the filtration power does not need to be too large);
(5) Upper layer filtration. Some finished fish tanks adopt this design, and there are filters and upper filter boxes in the tank. Simple structure, good filtering effect and convenient maintenance. By controlling the distance between the water inlet and the bottom of the cylinder within 5 mm, the sundries at the bottom of the cylinder can be easily sucked up;
(6) Multi-layer filtration, enhanced upper layer filtration, the filtration effect is doubled, because the multi-layer filter box can not only put filter cotton but also put filter material to cultivate nitrifying bacteria. The disadvantage is that the multilayer filter box is placed on the fish tank, which affects the appearance;
(7) Side filtration (the same is true for reverse filtration). Generally, the fish tank with side filtration will not be too small, because one side of the fish tank will be divided into a small area, and then this area will be subdivided into two or three areas, such as sedimentation area and clear water area. The filtering effect is good, but the disadvantage is that it takes up space in the tank, and the filter cotton must be replaced frequently, otherwise once the cotton becomes airtight, the pump may idle;
(8) The bottom filter must be a fish tank with a cupboard. It is generally believed that the bottom screen has many advantages such as strong filtering ability, easy maintenance and beautiful appearance. Generally, the bottom filtration of medium and large ornamental fish is definitely the first choice, and the only thing that can't be used in this way is the straw tank with CO2.
2. Select the filtered power.
Generally, the size of the water body is calculated first, and the unit of measurement is liter (L). Then multiply the water quantity by 6 to get the hourly flow value of the water pump, and the unit of measurement is L/h. This value will be marked on the water pump for filtering.
For example, a 60*30*35 fish tank, the actual water body is about 50L, and a 300L/H pump is enough.
In addition, if the cylinder is deep (for example, 80CM deep) or the water pipe turns a lot, the value can be added to 8 or even higher in calculation. When selecting a water pump for a deep cylinder, you should also look at the head parameter value.
5. How to choose the pump flow suitable for your fish tank?
1, water body size: No matter how standard and strange the size of your fish tank is, what you end up with is the water body of your whole fish tank (including the water in the filter).
Only by obtaining this water body can the filtered water flow required for fish tank filtration be calculated. 2. Types of fish: Not much to say. Simply put, the more active fish are accompanied by problems of digestion and feeding.
So more traffic is needed to deal with these problems. Relatively speaking, as quiet as that, the flow required is of course smaller.
3. Breeding density:100L water comes standard with a pump, and the flow rate is 1000 L/h ... But if your fish tank is overloaded, your pump flow rate is definitely not enough.
4. The gap between the technical reference of the water pump and the actual flow: the lift of the water pump refers to how high the water pump can pump. In other words, the height difference between the two floors is the lift required by your fish tank.
But in fact, when the pump with a lift of 1.5m is pumped to a point of 1.5m, the water flow is already zero. Because its technical reference only says that he can smoke that high, just like pressure measurement.
Therefore, in the selection, the lift must be greater than its parameter of 0.5 meters. This can ensure the water quantity of the pump, but it is actually less than his ideal water flow.
This is inevitable. 5. Pipeline construction: Even if your water pump is powerful, complicated pipelines will increase resistance and cause flow loss.
Therefore, in pipeline construction, change direction as little as possible, and the more turns, the greater the loss. The inner wall of the pipeline should be as smooth as possible.
Like some hoses, in order to be flexible at will, they are made into a circle shape. But this greatly affects the water flow.
If used for a long time, the pipe wall is easy to produce garbage. 6. Filtering method: There are many filtering methods. Among these filtration methods, depending on the difference between fish tank water level and filtration water level, the smallest ones are side filtration, reverse filtration and side filtration; Followed by up-filtration, the biggest gap is down-filtration.
The ideal state of the cartridge filter is zero difference, which is its structural advantage, because the cartridge filter is sealed. So there is no problem of atmospheric pressure, only the resistance of filter material affects the actual flow.
Select the water pump according to your filtration method. The greater the difference between the two stages, the greater the flow loss, so you should choose a large flow pump to make up for these flow losses.
