Can anyone help me choose an ornamental fish filter

If you have a large fish, the filtration system must be strong.

It is better to use the upper filter (that is, the upper filter box type you said) than the external filter barrel. However, the filter material that can be placed in the upper filter is limited, and it is impossible to have the best effect. So I suggest that you use the upper filter + outer filter barrel at the same time, so that the water can be clear and the fish is beautiful.

The ** of the outer filter barrel is more expensive, if possible, make a side filter yourself, so that it is the upper filter + side filter, which is a little better than the outer filter barrel, and it is cheaper.

Jiabao. brand. Anyway, it was from Guangdong Zhenhua Factory. It's more common to worry about it. Everyone uses it and it works well. There is also the floor rate. The effect is that the water quality is very clean.

Or you can use the Atman brand. Whether it's from Taiwan or Hong Kong. At least use the brand to rest assured that the price difference is 10 yuan. Thing is reliable.

The power is recommended to be larger. It also depends on how big the fish you raise. If the extra small fish didn't dare to ask for too much power. If it's a big fish, it's fine.

And it is not what kind of equipment is used, but what kind of ecological environment. Simulating an excellent ecological circulation system is the king. Just thinking about what kind of overthinking is just scratching the surface.

If you have the money, it is recommended to use an external filter bucket .At least the inside of the fish tank is beautiful. But the wattage is definitely very large. It's expensive.

It is better to use a submersible nose and connect the filter box type. That's what I use.

A good point for the upper filter box type.

When setting up a filter for your fish, first check the culture in the tank to determine the number of water cycles. Secondly, it is necessary to match the size of the water plant tank to determine the flow rate of the filter. Finally, when calculating the flow rate, it is more appropriate to multiply by one point and two times.

1.Check the culture condition in the tank to determine the number of water cycles.

a.Pure water grass tank, unraised fish – water cycles twice per hour.

b.Small fish are housed in aqua tanks – the water is recycled three times per hour.

c.Aquatic plants are densely planted and fish are dense – water cycles four or five times an hour.

According to the actual density of fish (the amount of manure pulled by the size of the fish).

2.Cooperate with the size of the water plant tank to determine the flow rate of the filter. If the size of the tank is 100 litres, 300 litres of water per hour is required.

3.When calculating the flow rate, please note that when the filter is activated for a period of time, there will be dirt blocking the filter media and reducing the flow of water, so in addition to cleaning the filter media regularly, it is more appropriate to multiply 1.2 times when calculating the flow rate. Therefore, in the above 100 litre aquatic plant tank, it is necessary to raise the lamp fish 300 litres per hour = 360 litres per hour filtration flow.

First, choose the appropriate type of filtration according to the breeding species, breeding method, etc.

Then choose the appropriate filtration power according to the size of the fish tank, the surrounding environment, etc.

Finally, according to the filtration type, filtration power and other parameters, select the brand model with appropriate cost performance.

What are the fish tank filters? How to choose? You have to address the root cause of the problem first.

The key to raising fish is filtration, and the key to filtration is to filter fish feces, the toxins in the water are produced by fish feces, and only by removing the ammonia of fish feces can the water be kept non-toxic, stable and clear, and the fish can be healthy and less sick. Due to the lack of eczemophytic area of nitrifying bacteria in the bare tank, nitrifying bacteria are very few, and fish feces can not be processed in time, the ammonia content of the water body is high, the fish are prone to disease and anorexia, and the water is also easy to be turbid, and moss and green algae are grown. Yongqing filtration will be helpful to understand.

Plug the air outlet! The water outlet should be properly blocked to reduce the amount of water output!!

If you really feel that the water flow is too big, you can blow the water mouth against the tank wall, we raise crystal shrimp like this.

1. Waterfall. Pros: Easy to use. Cons: May not work very well.

If you do want to use this, empty the box, fill it with the biochemical ring, and wash it regularly. The smallest two or three liters of water can be used, more than 30 pieces.

2. a filter barrel. Pros: Good effect. Cons: Expensive.

If you have the money to see the flow, you can use this, too small a fish tank is not good, the minimum is 30cm, ten liters of water, about 60 yuan.

3. Upper filter box. Pros: average, open, good dissolved oxygen, cheap. Disadvantages: not good-looking, blocking light.

Choose a submersible pump with a suitable flow rate, combine the boxes, fill the biochemical ring, and spread the biochemical cotton on it.

With closed external filtration, there will be many filter media in the filter barrel, and the filter media itself has about three functions: "physical filtration", "chemical filtration" and "biological filtration".

Physical filtration: mainly use nets and wool to remove larger debris in the water.

Chemical filtration: Activated carbon adsorption is used to remove organic matter and fish excrement that cause water turbidity.

Biological filtration: the use of microorganisms that reproduce on the surface of the filter media, or the activities of protozoa to filter, cultivate beneficial microorganisms to grow normally, it takes some time, but also have a proper environment, the quality of filtration effect, almost all depend on the ability of biological filtration. To get the most out of your filtering, you need to combine all three of these functions.
