Under the influence of today's society, fast-paced life and new lifestyles, many people choose to dig a small fish pond in their courtyard, make a rockery, and raise a few koi. Even if the epidemic is blocked at home, they can enjoy a beautiful and peaceful life. Building a fish pond in the courtyard and raising koi in the pond is also a very good way to accumulate wealth in Chinese Feng Shui.
However, I saw many ponds in small yards. The fish pond environment in which koi live is not very good. The water is green and mixed, and there is a strange smell from time to time. In severe cases, it will also cause koi to get sick and die. It completely goes against the original intention of building the fish pond, and there is no question of enjoying a beautiful and peaceful life.
This is obviously not possible. Only when the water quality of the fish pond is good can the koi grow healthily and achieve the best ornamental effect.
Misunderstanding 1: Sand tank filter can be used for fish pond filtration. In fact, sand tank filtration is also known as filter sand tank, sand filter canister, etc., because it was originally named after the use of quartz sand as the filter material. It is mainly suitable for swimming pools, hot spring pools, etc., and can filter out most solid particles, hair, etc. It is a physical filtration and has no biochemical function. It is not suitable for the water quality required by koi and is not recommended for use.
Misunderstanding 2: Just take medicine regularly for fish ponds. This view is generally obtained from farmers such as large soil pits and earth ponds that breed edible fish. However, the breeding density is high and does not require ornamentation. Moreover, it is a soil pit, which cannot be filtered, or the filtration cost is too high, which is not suitable. It can only be used to sprinkle medicine regularly to relieve it. After the fish grows up and sells it, the water will be changed. This is incorrect for the koi fish pond in the courtyard. It is generally not recommended to take medicine frequently in the fish pond. Too large doses will cause irritation to the koi and affect the water quality. It mainly relies on the filtration system. The medicine is only used in combination when there is a problem with koi or water quality.
Misunderstanding 3: Water circulation can play a filtering role. The so-called saying that running water does not rot. Many people have this misunderstanding, thinking that as long as the fish pond water is circulated and flows, it can achieve a clear effect. In nature, flowing water is injected with live water, and rivers and streams have source, so there is a sentence like "Where is the clear channel so clear, only the source of live water comes" For fish ponds, they are stagnant. Some bacteria, excrement, etc. produced by koi will not completely disappear due to flow cycles and cannot fundamentally filtration effect.
Misunderstanding 4: Outdoor fish pond filtration and indoor fish tank filtration are the same. In fact, there is still a big difference between the two. The fish tank is small in size, and indoors, the ecosystem is relatively simple. The outdoor fish pond is relatively large in size and has a complex ecosystem. It generally has rockery, plants, etc., and is greatly affected by the outdoor environment, so a complete and professional outdoor fish pond filtration system is needed for comprehensive purification.
Misunderstanding 5: Nitrifying bacteria have the effect of decomposing feces. Many people believe that regular investment of nitrifying bacteria in the fish pond can play a very good role in decomposing feces, which is actually wrong. Feces are decomposed by aerobic bacteria. nitrified bacteria only degrades components such as nitrite and ammonia produced after being decomposed, and cannot directly decompose feces. Therefore, do not put the important task of purifying feces in fish ponds on nitrified bacteria. The fish manure and other impurities at the bottom of the pond can be cleaned regularly with the sewage suction machine at the bottom of the pond.
Misunderstanding 6: stainless steel filter is better than plastic filter. This is a relatively one-sided understanding. The durability of stainless steel and its response to complex outdoor use environments are definitely much stronger than plastics, and they are not easy to age.But the most important thing is the inner core of the equipment. Some stainless steel filters are better for the shell. They still use filter cotton and brushes inside. It is recommended that you choose outdoor fish pond filter equipment or more comprehensive (such as integrated nano-suspended filter element, free disassembly, membrane filtering bacteria, ultraviolet sterilization, etc., which can achieve sterilization, algae removal, bacteria cultivation, ammonia nitrogen reduction and other functions)
Misunderstanding 7: After the water quality is improved, there is no need to turn on the purification equipment for a long time. Set up a start-stop switch and turn on for several hours a day. This view is also wrong. Just like people breathe air, after the air is temporarily purified, harmful gases may be produced at any time. As long as such gas is inhaled, human health will be affected. The same is true for fish ponds. Do not turn off the purification system immediately after the water quality is improved, but should be turned on continuously, so that the water quality can be kept clear at all times and create an ideal living environment for koi.
As long as you pay attention to the above major misunderstandings, when you choose a filtering system, you can have a clear idea and it will be very simple to raise a pool of beautiful koi.
