Filter media for koi pond

The filtration system plays the role of purifying the water in the fish tank and is an indispensable and important part of the fish tank. The filtration system of the fish tank can be divided into water pump, physical filtration and biochemical filtration.

Generally speaking, the first level of fish tank filtration - white cotton , is physical filtration.

The main function of physical filtration is to separate the impurities in the water (fish feces, bait residue, etc.) to ensure that there are no large particles in the water and reduce pollution sources. Fish excrement and feed residues in water for a long time will be decomposed by heterotrophic bacteria, resulting in highly toxic ammonia. When the ammonia content in water is 0.05-0.2ppm, fish will be acutely poisoned and die quickly.

Filter materials other than white cotton and filters are all biochemical filter materials, including: ceramic rings, glass rings, bacterial houses, rattan cotton, etc. Biochemical filter material is the place where biological filtration occurs, and its main function is to cultivate nitrifying bacteria.

Nitrifying bacteria can decompose ammonia in water, converting ammonia into less toxic nitrite, while nitrite is converted into almost non-toxic nitrate by another nitrifying bacteria in an aerobic environment, which is highly toxic The process of converting ammonia into nitrate, which is almost non-toxic, is called nitrification. The reason why it is called biochemical filtration is that it purifies the water from a biochemical perspective to keep the water in good condition.

1. Biochemical cotton

Biochemical cotton is also a widely used filter material, mainly for the effect of biochemical filtration. Compared with filter cotton, it is denser, not easy to damage, and much thicker, so that there is enough space for parasitic nitrifying bacteria. It can also filter out some large foreign bodies. Biochemical cotton is widely used in upper filter, external filter and internal filter.

The maintenance frequency of biochemical cotton is much less than that of filter cotton, usually about one to two months, because a lot of nitrifying bacteria are parasitic in biochemical cotton. Fluctuations in water quality.

2. Jap Blue Filter Mat

Jap Blue Filter Mat is a kind of filter material with high usage rate now. It has high resistance to resistance, water resistance, light resistance and flame retardancy. In addition to the water permeability and air permeability required by traditional filter materials, the service life of rattan cotton is also worth mentioning. It can be washed and recycled many times and has a long service life. Non-blocking, non-deforming, and reusable after cleaning.

Experts have analyzed the dense pore gap and softness of Jap blue filter mat

, which are the most suitable nitrifying bacteria for cultivation. It has the best effect on decomposing excrement and feed residues, improving water quality, and filtering and cleaning, thereby reducing fish mortality.

3. Filter Brushes

Generally, large ground tanks or fish ponds will use brushes, which have good toughness, are not easily deformed, and can be used repeatedly for a long time. The cross-shaped filament space structure greatly enhances its adsorption capacity, making it easier to intercept particulate matter and cultivate nitrifying bacteria. While the surface area is increased, the number of film hangings is more powerful (there are more places for nitrifying bacteria to grow), which strengthens the filter brush. physical filtration and biological filtration functions. In the same volume of filter tank or filter tank, the effect of filtering and stabilizing water quality is more significant, and the number of maintenance is less.

4. Bio Ceramic Ring

The surface of the ceramic ring is covered with tiny pores, which are suitable for the reproduction of nitrifying bacteria and mainly have the effect of purifying the water quality of koi culture. Bio Ceramic Ring will be very efficient in small filters, because ceramic rings are divided into large and small rings, which can be selected according to the size of the container. Ultra-high-purity, ultra-dense porous bio-glass medium active ceramic ring can effectively protect the ecological balance of the fish tank and stabilize the water quality. The ceramic ring has a long life and is resistant to corrosion. Using a ceramic ring can also reduce the frequency of water changes in your tank, keeping your fish and plants healthy. It is non-toxic and harmless, will not change the PH and KH values of the water body, and will not cause any harm to the feeding water body.

The ceramic ring does not chemically react with any agent, and is the best culture for benign microorganisms. The adsorption capacity of the ceramic ring is very strong, and it can be applied to any freshwater ornamental fish.

5. Functional Mineral Stone

Our Functional Mineral Stone is activated medical stone, which contains many beneficial soluble trace elements. Medical stone was widely used in human drinking water equipment in the early days, and is now used in aquarium filtration systems to adjust water quality.

It has a strong adsorption capacity, has a two-way regulating effect on the PH value of water, and releases a large amount of beneficial trace elements, which is of great benefit to the breeding of ornamental koi fish and the hatching of young koi fish. , it can be placed in the position equivalent to the glass ring. It needs regular cleaning of the surface of the dirt, about once a year to replace.
