Because of its small size but good filtering effect, it is nicknamed "water leprechaun" by aquarium enthusiasts.

The water leprechaun is a built-in filter device that needs to be connected to an oxygen pump and an air hose. It can be adsorbed on the wall of the aquarium. The principle is to use the water-lifting effect generated when the bubbles rise in the water to filter, which can effectively excrete through adsorption. In addition, the bacteria in the filter cotton can effectively decompose organic matter, so as to achieve the purpose of biological filtration in a small space.

The principle of the small finished gas lift filter is to use the water-lifting effect produced by the bubbles rising in the water. It is driven by an air pump. The power is small but the effect is large. Suitable for small fish tanks and keeping small fish.

1. The water leprechaun。can be adsorbed on the wall of the aquarium. The principle is to use the water-lifting effect generated when the bubbles rise in the water to filter, which can effectively absorb excrement and residual bait. In addition, the bacteria in the filter cotton can effectively decompose organic matter. , so as to achieve the purpose of biological filtration in a small space.

2.The water leprechaun can be connected with an air pump or a water pump to achieve the dual functions of oxygenation and filtration. But the power is small, it is generally suitable for small cylinders, and it can also be used as an auxiliary filter for large cylinders.

3.The Water leprechaun is connected to the air pump mainly for biochemical filtration, that is, as a bacterial bed. Sponges can absorb fine particles, but have poor adsorption for larger residual bait, feces, etc. The advantage is that the water flow is controlled by airflow, small and slow, and will not cause shock to small fish.

4.The Water leprechaun connected to the water pump is mainly a physical filter. Due to the dense pores of the sponge, the filtering effect is very good. But the disadvantage is that the sponge needs to be cleaned frequently, which is estimated to be more than twice a day; and the water flow is controlled by the water pump, which is generally relatively large.

1. Regarding the earliest water leprechaun, they will have a disadvantage, because they are biochemical cotton, and their weight is very light, coupled with the effect of oxygen supply, it will make the bottom suction cup of this biochemical cotton difficult Being fixed, it is easy to float to the water surface for a long time.

2. Because they are hollow, a fish-breeding expert came up with a solution, which is to add some ceramic rings to the hollow inside of the filter cotton, and put the oxygen head at the bottom of the ceramic ring, just like the filter in the anti-gas lift. The material installation method is used to increase the weight of the water leprechaun, so that the suction cup at the bottom is not used, and it also plays a certain role in increasing and cultivating nitrifying bacteria.

3. After a certain reform, the water leprechaun became a round-shaped polygonal cotton-changing cotton with a thick base and a white plastic tube on the top, and later evolved into a double-ended biochemical cotton, making the The filtration effect has doubled, but in fact, it is a matter of changing the soup instead of the dressing. In principle, it is the same, and it is also used to filter out impurities and provide oxygen.

4. Until now, there is a water leprechaun with a biochemical filter material that can be added on the market. The outside is a plastic shell, the bottom layer is added with biochemical filter material, the upper layer is added with white cotton or biochemical cotton, and there is oxygen supply in the middle.

1. Therefore, no matter what form the water leprechaun are based on, their filtering effect will not be very good after all, and they can only be adapted to relatively small fish tanks, such as some ultra-white grass tanks, we can add plug-ins or filter cartridges, while the For a small aquarium with a fish tank cover, if the filtering effect is not very good and other filtering forms cannot be added, it can be supplemented by water leprechaun

2. Or the cichlid ornamental fish in small and medium-sized fish houses are used in breeding tanks, while in medium and large fish tanks, water leprechaun are rarely used. Even if they are useful, they are basically only for oxygen flow when supplying oxygen. It can be upward, so that the water flow in the fish tank will not be too messy, and it can be used for very little filtering.

3. The other is that when usingwater leprechaun in our small fish tank, we have to adjust the supply of oxygen according to the cleanliness of the fish tank. If the impurities in the fish tank cannot be effectively absorbed by thewater leprechaun we can remove the oxygen. If the amount is appropriately increased, we can observe this through the precipitation of impurities at the bottom of the tank and the reaction of the ornamental fish.

4. If the situation is the opposite, the amount of oxygen in our fish tank is too high, causing debris to fly around. At this time, we must reduce the supply of oxygen appropriately, which requires us to take care of ourselves according to the actual situation. Going to adjust, we can't leave the water leprechaun installed and leave it alone.

5. No matter what kind of water leprechaun, their properties will still be like a built-in filter, that is to say, even if their filtering effect is good, the impurities in the fish tank will always stay in the inside of the fish tank, and all kinds of organic matter Just got concentrated without being effectively removed.

6. Even if the best water leprechaun now have some biochemical filter materials added to them, the biochemical filtering effect they can play is not very large, unless the water area of ​​the fish tank is very small or the fish stocking density is very low.

7. But in a very small fish tank, the water leprechaun will occupy too much space, which is also a drawback of thewater leprechaun, so we have to make good use of it according to our actual situation.

8. Another one is that there will always be too much debris on the bottom of the water leprechaun before, and every once in a while, if the water leprechaun works well in the initial stage, but the water quality of the fish tank cannot be guaranteed in the later stage, then only It proves that the adsorption capacity of the water leprechaun has become saturated, and we need to clean it regularly.

9. It’s just that the current water leprechaun can only clean the upper filter cotton, but this also requires the entire water leprechaun to be pulled out, so the operation is similar to the previous built-in filter, and it still damages the nitrifying bacteria. of.

10. If we still use the old water leprechaun, basically all the nitrifying bacteria are gone after one wash, and we have to re-cultivate it, which is no different from a small fish tank with only a piece of filter cotton.

11. Therefore, this thing is of a tasteless nature. Let's not use it. Some small fish tanks must be used due to limited conditions. If it is used, there will still be many drawbacks. I usually only use it in the breeding tank of cichlid ornamental fish, and the effect is still ok. Then there is the small fish tank with extremely low stocking density. If you are too lazy to add any filter device, just throw a water leprechaun in it, and clean it regularly when it is dirty. Occasional use in fish tanks where moss water is grown.

Generally speaking, the daily maintenance of water leprechaun need not be very frequent, mainly depends on its use environment and individual model -- rice shrimp, low-density small fish, breeding tank usually need not be too frequent cleaning or replacement, in order to reduce water fluctuations. On the other hand, the auxiliary filtration of langao shrimp, or medium and large fish, which mainly focuses on the physical filtering effect, requires more frequent maintenance, generally cleaning when most of the surface is covered by dirt.

For pure fecal suction models, simply clean the collection tank. If it is black biochemical cotton, which is popular in the market, it needs to be washed in water at room temperature. Do not use hot water or any form of detergent to avoid the death of bacteria and even poison the creatures in the aquarium. If it is used as the only filter, please take the water from the cylinder and wash it outside. In case of deformation, replace the head in time.

Some styles of water fairies are "white cotton", which has better adsorption effect on dirt and is not easy to produce secondary pollution, but white cotton itself has almost no ability to cultivate bacteria, and the effect after washing is very poor. It is recommended to buy this type of people at the same time to buy large white cotton, and leave cotton size reference before water fairies are used. Easy to replace later.
