Ground tank koi rattan cotton bacteria house which is better

Nowadays, most of the fish are raised in bare tanks, and the advantage of bare tanks is that they are easy to clean, and dirt is not easy to accumulate at the bottom of the tank. However, due to the lack of nitrifying bacteria in the tank, the self-cleaning ability is limited, if the density of the fish is large and the feeding is too much, and the fish feces cannot be absorbed in time, the water body is easy to be turbid in many cases. Because the BB of the fish cannot be decomposed and transformed by nitrifying bacteria in time, the ammonia nitrogen in the tank exceeds the standard, and the fish is easy to get sick or even die.

The Yongqing filtration system cultivates a large number of nitrifying bacteria in the biochemical mesh plate and bottom sand in the tank to decompose and treat fish feces in time, and generates a directional water flow under the net plate to guide the dirty things to the water inlet to be pumped out and filtered out. So as to keep the water stable and clear, so that the fish are healthy and less sick, and can grow moss and green algae in the fish tank. Yongqing filter to find out.

The system has an automatic cleaning function to clean the bottom of the tank, so that you can enjoy the fun of fish farming with ease.

Simple filtration is not able to remove the algae and bacteria in the water, unless you are using reverse osmosis membrane to filter, but this is obviously unscientific, not to mention how high the cost of osmosis is, if the bacteria and algae in the water are filtered out at the same time, the organic matter in the water is also filtered out, the pure water is not able to feed fish, the landscape water special equipment produced by Delitong Water, the use of physical water treatment methods, without any chemical agents, can achieve sterilization and algae killing, decomposition of ammonia nitrogen, improve the effect of dissolved oxygen, Fish have to live in such an environment to be healthy, and there is no need to say the details of the situation

In fact, the actual effect of these filter media is almost the same, but there are differences in service life, cleaning cycle, etc., as for the surface area, there are also differences, but for the bottom filter, this difference can still be ignored.

For example, if one person's salary can support 10 people, but he has to support 20 people, of course he can support them, but the living conditions are much worse, and he can support 10 people.

But if you barely raise 20 people, you might be skinny, and as an analogy, you should understand that hehe, or 10 strong people, can do a good job, but 20 weak people may not be able to do a good job.

Because nitrifying bacteria are the same.

It doesn't have to be a quantity, if it were me, I'd be more concerned about quality.

The glass floor tank is also a good choice for domestic koi. Necessary equipment: aerobic pump, water pump or surf pump (slightly different depending on the structure of the filtration system), water thermometer, wall lamp, and can also be equipped with a digital central control. The filter materials are, physical filter cotton, bacterial house, rattan cotton (the same effect is also magnetic ring, plastic balls, etc.), activated carbon, in order to adjust the pH value or water hardness, you can also put some coral sand in the filter tank (packed in a bag).

Rattan cotton is generally used as the first stage of filtration, filtering out larger impurities in water, and physical filtration has more functions; Biochemical cotton and bacteria are mostly used as culture beds for nitrifying bacteria, focusing on biofiltration. Generally, it is used for the bottom filter of fish ponds or large tanks, and the effect is good, but small tanks are not suitable.

Of course, the effect is the same, good rattan cotton is better for nitrifying bacteria, and it can be placed alternately layer by layer.

Two layers of rattan cotton sandwich a layer of sticks. Now the swing method is popular.

Why can't you use both?

The bottom of the water inlet part of the bottom filter (the physical filtration part of the first sink) can be placed in a layer of bacterial house, then a layer of rattan cotton and a layer of bacterial house, the top layer of rattan cotton (a few centimeters above the water surface), and a filter cotton can be placed on top of the rattan cotton. An oxygen tray can be placed at the bottom of the biochemical filter tank, and the rest of the space can be fully placed in the bacterial house, or a layer of bacterial house and a layer of rattan cotton, and activated carbon can be placed below the water surface of the uppermost part. Needless to say, the water pump is sufficient.

All filter media should be soaked for a period of time before being put in, and the activated carbon should be rinsed before being put in. You can also put some coral sand according to the situation to adjust the pH value. The porcelain ring can also play the role of a bacterial house, but I personally think that the effect is not as good as that of rattan cotton and bacterial house.

Hair brushes, this one is the most affordable, the glass ring is too expensive. Filtering is not small, bro.

It is recommended that you use a glass ring with a layer of filter cotton on top.

Rattan cotton is filtered for dirt.

The glass ring is used to culture nitrifying bacteria.

The brushes are used to brush the moss on the walls of the tank, and each has its own purpose.

The filter material is mainly used to cultivate nitrifying bacteria, such as bacterial houses, quartz balls, ceramic rings, biological rings and even rattan cotton. The key is to take personal experience as a result, the main thing is that the quality is good, the water permeability is good, and the pH value of the filter material is suitable for the local water quality. The main thing is that the filtration should be strong, and then the physical filtration should be done well, and the filter material is just a hotbed for cultivating nitrifying bacteria.
