Benefits of Zeolite for Shrimp Pond

Zeolit benefit for shrimp pond

Shrimp ponds are businesses in the fishery sector that involve ponds containing freshwater, saltwater, and brackish water. Shrimp is one type of filter animal so that water quality is crucial for the results obtained by farmers. Potential shrimps to be cultivated in ponds are tiger shrimp (Penaeus monodon) and vaname shrimp (Litopenaeus vannamei). Both are able to tolerate salt levels between 0 to 45 percent.


Zeolites are natural minerals made from aluminum silicate groups that are hydrated by alkali metals and alkaline earth. The zeolite mineral is gray to bluish. Clinoptilolite is a type of natural zeolite mineral that has many uses.


In aquaculture, Clinoptilolite can be used to help control the quality of the soil at the bottom of a pond. Clinoptilolite forms like crystal and has a variety of colors, namely white, yellow, pink, and pale brown.


In this article, Nusagri discusses the benefits of zeolite for shrimp ponds. Nusagri has also published related articles,  Zeolite as ammonia adsorber in pond. Please refer to the article.

Pond water quality is an important thing that must always be considered. According to research, if environmental conditions such as water quality are not in accordance with the standards for cultivation it will cause death and ultimately losses in aquaculture. Water quality management is a way to maintain water quality parameters in accordance with quality standards for cultivation. These parameters are an indicator to see the quality of water, such as dissolved oxygen (DO), free carbon dioxide (CO2), pH, temperature, brightness, salinity, ammonia, and nitrite.

Dissolved oxygen should be sufficient. Scientists generally agree that aquatic animals need dissolved oxygen at a concentration of 5.0 mg / L or more to be able to live and develop. However, the amount of oxygen needed can also vary depending on how large or complex the animal is and where it lives. The greater the dissolved oxygen value, the better the water quality. The highest difference in dissolved oxygen concentration is found in waters that have high plankton density and vice versa. Most of the waters that have low oxygen levels are caused by a variety of complex factors from natural to man-made factors. The solubility of oxygen in water is influenced by several factors including temperature, salinity of the waters, movement of water on the surface of the water, the surface area of open waters, atmospheric pressure, and the percentage of oxygen around it.


When the concentration of dissolved oxygen is low, carbon dioxide levels can inhibit the entry of oxygen into pond water. The normal range of carbon dioxide is from 1 to 10 mg / l. If carbon dioxide exceeds 10 mg / l, the water quality is not good.


Too high pH is not good, a pH above 8.5 causes ammonia in the pond to be toxic and raises hydrogen sulfide around it which is also a toxic substance, so don’t overdo it.


Temperature or temperature is one indicator of the success of shrimp farming. For this reason, temperature fluctuations must always be watched out for by farmers, because sudden spikes or decreases in temperature can inhibit shrimp growth and can even make shrimp die.

It should be noted by farmers that the optimal temperature for shrimp to grow and develop is in the range of 26 to 30 degrees celsius. As for the drastic temperature change that can be overcome by shrimp is no more than 2 degrees celsius. If the pond temperature decreases until it reaches 25 degrees Celsius, it can cause the digestibility of food by shrimp will be hampered, this will later influence the growth of shrimp. Vice versa, if there is a surge in temperature to reach 30 degrees Celsius or more, it will trigger stress on shrimp. The stress experienced is due to high-temperature changes that cause shrimp oxygen demand to increase.


To avoid stress on shrimp, pond entrepreneurs are required to always check the level of water salinity routinely. In general, the ideal shrimp ponds are shrimp ponds that have a salinity level of around 10-30 ppt.


Zeolite is useful for conditioning pond water quality to conform to shrimp pond standards. Various benefits of zeolite minerals for ponds, namely:


• Because it has a high absorption power, zeolite minerals can reduce gases in the remaining shrimp feed (not eaten), as well as gases originating from the metabolism of other organisms that live at the pond bottom.

• Zeolite minerals are able to bind heavy metals in water or pond bottom soils that can threaten the survival of fish/shrimp, such as Pb, Fe, Hg, Sn, Bi, and AS.

• Because zeolites have a high calcium content, shrimp in ponds can be prevented from soft skin diseases.

• Maintaining the stability of the water temperature, as well as maintaining the degree of acidity (pH) of water in a pond.

• Increase the level of dissolved oxygen in the water

• Helps the growth of phytoplankton in ponds, so that natural food for shrimp is always maintained.

Zeolite as Ammonia Absorber in Pond

Ammonia reduced from pond

Ponds are part of extensive aquaculture. The pond is one type of habitat that is used as a place for brackish water aquaculture activities located in coastal areas. In general, ponds are usually directly related to the maintenance of tiger prawns, although actually there are still many species that can be cultivated in ponds such as milkfish, tilapia, grouper, white snapper and so on.

However, a problem that is often encountered in pond aquaculture activities is the concentration of ammonia which has a bad effect on animals on the pond. Ammonia will be toxic to fish if allowed to accumulate in large quantities in ponds. When ammonia accumulates to toxic levels, fish cannot extract energy from feed efficiently so that eventually the fish will become lethargic, sick, and die.

Ammonia in water exists in the form of NH3 molecules and in the form of ammonia ions in the form of NH4 +. Both forms of ammonia are very dependent on pH conditions and water temperature. If the balance is changed, such as the pH value in one of the descending parts will bring about the addition of ammonia molecules. The balance between NH3 and NH4 + is also influenced by temperature. Under certain pH conditions, toxic ammonia will appear in warm water compared to cold water. In addition, the level of toxins from ammonia is also influenced by the oxygen content in the water.

Measurement of ammonia concentration will give a glimpse of the conditions at the time the water sample is taken. But measurement at all is ineffective because the relationship between these processes is very complex because the rate of change varies throughout the year and results in a measurement pattern.

Nitrogen compounds usually come from the atmosphere, water supply, food scraps, dead organisms and from the metabolism of aquatic animals. The amount of nitrogen gas or nitrogen oxides coming from the atmosphere is generally very small. Therefore pond water pollution by nitrogen originating from the atmosphere is very unlikely. Pollution of aquaculture water by nitrogen compounds is generally caused by nitrogen compounds derived from the remnants of fertilization, dirt and other substances contained in water sources. According to research, the main source of nitrogen compounds in aquaculture is the result of aquatic animal metabolism.

Reduce ammonia from fish pond

The main source of ammonia in ponds is fish excretion. Fish will break down the protein in the feed and excrete it through the gills and feces. The amount of ammonia that is excreted by fish depends on the input of feed given in the culture system, the addition of such as the addition of feeding rate. Ammonia enters the pond also from the decomposition of organic material such as leftover food or algae and other dead aquatic plants carried out by microbes and fungi.

The danger or not the level of ammonia poison can vary depending on the type of fish because some more can survive. In addition, other factors such as water temperature and chemical factors play an important role. For example, ammonia (NH3) constantly changes to ammonium (NH4 +), and vice versa. The amount of each relative depends on the temperature and pH of the water. Ammonia is very poisonous, while ammonium is relatively harmless.

Ammonia control is a rather complicated problem in fish farming. Medications carried out in a situation can be toxic to fish life. Fish are very sensitive to sudden changes that occur in water. Eliminating ammonia must be done without dramatically changing the pH and it is best done without using harsh chemical additives. The use of zeolites is one of the safest ways to control ammonia levels in ponds.

Physical and chemical ion exchange is considered to be the foremost and effective way to control ammonia. The use of Zeolite and Clinoptilolite has been used successfully as an ion exchange medium to remove ammonia. Cations in the pore help neutralize the zeolite load. These cations can move freely so they can easily exchange ions. The mechanism of cation exchange is largely determined by the size, charge, and type of zeolite. Natural zeolites consist of Aluminum Silicate, capable of adsorbing and exchanging gases, whereas clinoptilolite are a kind of zeolite in which ammonia gas is adsorbed and ammonia ions are exchanged. Clinoptolites are more beneficial when compared to artificial zeolites.

Descriptions are also influential in capturing ammonia in ponds. Zeolites have a high capacity for adsorbing. The adsorption mechanism that occurs includes physical adsorption (Van der Walls force) and chemical adsorption (electrostatic forces). The absorption capacity of zeolite depends on the number of pores and surface area. Only molecules smaller than the zeolite pore can be adsorbed.

Thank you for reading the article about controlling ammonia levels in ponds. The conclusion that can be obtained from this article is that zeolite is one method that can be used to safely control ammonia in a pond based on its porous nature and is able to exchange ammonia ions.

Natural and Synthetic Zeolite

Zeolites are hydrated aluminosilicate compounds consisting of SiO4 and AlO4 tetrahydra bonds connected by oxygen atoms to form a skeleton. In the zeolite framework, each Al atom is negative and will be neutralized by bonds with easily interchangeable cations. The easily interchangeable cations present in this zeolite framework influence the adsorption process and the thermal properties of zeolites. In addition to the type of cation, the zeolite adsorption ability is also influenced by the Si / Al ratio and the geometry of the zeolite pores, including of inner surface, pore-size distribution, and also pore shape. Zeolites occur naturally at the surface of the soil. At present many types of natural zeolites have been found and grouped according to their structural similarity.

Zeolite is one type of rock containing several alumino silica minerals that are hydrated from alkaline cations and alkaline soils which have a porous structural framework, are easy to boil and expand when heated (Anwar, 1987). Zeolites have a three-dimensional structure with cavities in which contain metal ions, the zeolite molecular formula, namely Mx / n [(AlO2) x (SiO2) y] mH2O where M is a validation cation n, (AlO2) x ( SiO2) y is a negatively charged zeolite framework, while x and y are total tetrahedral numbers per unit cell and the x / y ratio is always around 1 to 5, and H2O is the hydrated water molecule in the zeolite framework.

Zeolites are composed of elements of aluminum (Al), silicon (Si), oxygen (O2), and contain cations (+ ions) and water (Ballard, et al., 1988). The more complete chemical composition of zeolite consists of Silica (SiO2) 68.3%, Aluminum Oxide (Al2O3) 12.3%, Iron (Fe2O3) 0.1%, Calcium (Ca) 4.3%, Magnesium (Mg) 1, 1%, Sodium (Na2O) 0.3%, and Potassium (K2O) 1.0%.

Zeolites can be obtained through two types of sources, natural zeolites and zeolite synthesis. Natural zeolites are formed due to the complex chemical and physical processes of rocks undergoing various kinds of changes in nature. Geochemists and mineralogists has estimated that zeolites are volcanic products that freeze to volcanic rocks, sedimentary rocks and metamorphic rocks which subsequently undergo weathering due to the effects of heat and cold. As a natural product, natural zeolites are known to have very varied compositions, but the main components are silica and alumina. In addition to these main components, zeolites also contain various minor elements, including Na, K, Ca, Mg, and Fe.

Apart from its wide application, natural zeolite has several disadvantages, including containing many impurities such as Na, K, Ca, Mg and Fe as well as poor crystallinity. The presence of these impurities can reduce the activity of zeolites. To improve the character of natural zeolites so that they can be used as catalysts, adsorbents, or other applications, activation and modification are usually done first.

Synthetic zeolites are zeolites that are engineered in such a way as to obtain better character than natural zeolites. The basic principle of synthetic zeolite production is its component consisting of silica and alumina, so that it can be synthesized from various raw materials containing the two components above. Minor components in zeolites can also be added easily using pure compounds, so synthetic zeolites have a fixed composition with a high degree of purity.

the difference between natural zeolites and synthetic zeolites is:

1. Synthetic zeolites are made from chemicals and natural ingredients which are then processed from the natural seed body.

2. Synthetic zeolites have a ratio of silica and alumina which is 1: 1 and on natural zeolites up to 5: 1

3. Natural zeolites are not separated in an acidic environment like synthetic zeolites

Effect of Mixing Zeolites with Compost to Improve Soil Quality

Zeolites are known for their advantage on numerous aspect. They are utilized in numerous things incorporate restorative, car, and horticulture. In farming, characteristic zeolites have been utilized as feed added substance, water conditioner, soil conditioner, and in any event, for developing vehicle for hydroponics. Ranchers utilized zeolite in light of current circumstances. It could enable their plants to have more supplements or tie substantial metals that cause terrible impact on fish, or decreasing smelling salts creation from creature dung.

Advantage of normal zeolite in agribusiness have been referenced in our article previously. If you don’t mind check our article about Uses of Zeolite in Agriculture, and check our full articles at Nusagri’s Blog. In this article, we will examine about zeolite application in manure for plants. The conversation included properties of zeolite and how zeolite influence the development of plants.

Characteristic Zeolite joined well of lava ejection. Geochemists and mineralogists gauge that zeolites are the result of solidified volcanoes into volcanic rocks, sedimentary rocks and transformative rocks which in this manner experience enduring because of the impact of warmth and cold so zeolite minerals in the end shaped.

Compost has long been known as an organic fertilizer which is very important for soil fertility. Long before chemical fertilizers were used, farmers used food scraps mixed with manure as compost. The emergence of chemical fertilizers makes farmers reluctant to use compost because chemical fertilizers are far more practical and efficient. However, excessive use of chemical fertilizers without compost coupled with it turns out to have side effects reduce the ability of the soil to support plant growth. Soil tends to get harder and soil pH decreases. Improvements in technology for making chemical fertilizers also have a negative impact by reducing or even eliminating levels of micro elements that are important for plants.


The negative effects of chemical fertilizers have encouraged agricultural experts in developed countries to start advocating for the use of compost as a substitute for chemical fertilizers and contributors to organic matter in the soil. Compost contains more diverse types of nutrients including micro nutrients such as copper, iron, zinc, and manganese. The amount of soil organic matter continues to decrease due to the decomposition process. To maintain the amount in the soil it is necessary to add organic material from the outside, for example by the entry of fallen leaves into the soil. However, the process is very slow, especially on land that is used for intensive agriculture. So the addition of compost to agricultural land is an effective way to maintain soil organic matter content. Compost contains more diverse types of nutrients including micro nutrients such as copper, iron, zinc, and manganese.

The problem that arises from the use of compost is that the low content of nutrients causes the addition of compost as a source of nutrients requires very large amounts. To offset one kilogram of urea, for example, it takes about 20 kilograms of animal manure compost. That is also the availability of nitrogen isn’t as fast as urea fertilizer. In addition, the nitrogen in compost easily evaporates into the atmosphere causing a foul odor and leaching of nitrogen through rain water. More than half of the nitrogen contained in chicken manure is lost to the atmosphere if the composting process is carried out for more than 2 months in the open air.2 To improve nitrogen efficiency in animal manure, reducing nitrogen loss is an important effort both in terms of economic and environmental aspects. For the above purpose, zeolites which have the ability to absorb nitrogen are expected to reduce nitrogen loss while reducing foul odors.

Processing Livestock Waste with Zeolite

Animal husbandry is an important aspect of our lives. Many of the products we consume daily come from animal husbandry, such as meat, eggs, wool, cheese, yogurt, and so on. Therefore, livestock business throughout the world will not be quenched. Farms are managed by farmers by raising livestock to be used as multipurpose products. Some of the most common livestock raised are cows, chickens, sheep, goats, pigs, rabbits, and so on. Farming trends also vary by region, depending on what is consumed the most there.

The process of raising livestock in general is to meet the needs of animals such as feed and a comfortable environment. The aim is to make animals more productive. The more productive the livestock, the more profitable the breeder.

The process of raising livestock is also closely related to livestock waste. Livestock waste is all the remaining waste from livestock business activities, either in the form of liquid waste, solid waste, or in the form of gas. Solid waste is all waste in the form of solid or in a solid phase (cattle dung, dead cattle, or entrails from slaughtering herds). Liquid waste is all waste that is in the form of liquid or is in a liquid phase (urine, water washing equipment). Waste gas is all gas in the form of gas or is in the gas phase. The presence of pollutants in the water in an abnormal amount resulted in water being declared polluted. One cow weighing 400-500 kg can produce 27.7-30 kg / day of solid and liquid waste. Among these three types of livestock waste, liquid waste is the most widely produced waste and liquid waste from the livestock business activities is believed to still contain a lot of mineral substances that can be used by microalgae for their growth.

Zeolites are a group of minerals produced from hydrothermal processes in igneous rock. This mineral is usually found to fill gaps or fractures from the rock. In addition, zeolites are also deposits of volcanic activity that contain many silica elements. At present the use of zeolite minerals is increasing, from use in small industries to large scale industries. In developed countries such as the United States, zeolites are truly utilized in industry. Because of the properties possessed by zeolites, these minerals can be utilized in various fields, such as in the industrial sector, namely as materials that can be used to help treat factory waste. The problem of industrial waste is increasingly troubling the community, so many efforts have been made to overcome this waste pollution, either by reducing the volume of wasted waste or by recycling it again.

Zeolites have properties that are capable of exchanging cations, filter of fine-sized objects, absorbent of gas or liquid and as catalyst, can also prevent ammonia poisoning due to the use of non-protein nitrogen (NPN) material, and absorbent organic compounds. Zeolite has a high absorption which is useful as a catcher for various free chemical elements so as not to pollute or poison the environment, animals and humans. Zeolites in the field of animal husbandry used as food additives in chicken, pork and beef rations. Zeolites play a role in preventing and treating diseases of the digestive tract such as diarrhea, increasing body weight, improving feed conversion, reducing the highly pungent odor from impurities and preventing mold fungi during storage.

Zeolite can be used to obtain pure methane gas from waste in the form of rotting waste or waste from a farm. The dry methane gas is then flowed through tubes containing dried zeolite mineral powder, usually used is a type of kabasite or erionite zeolite, into the tube CO2 gas will be absorbed and bound by zeolite so that it will produce pure methane gas.

Utilization of zeolite to process cattle farm waste is by mixing it directly into cow dung. Zeolite will absorb cations and / or anions that cause odors that are in the dirt so it will not be easily separated. Zeolite is also able to agglomerate manure so that it can accelerate the process of ripening cow dung as organic fertilizer.

The types of zeolites suitable for animal husbandry applications are Clinoptilolite, Mordenite, and Khabazit. The three types of zeolites are alkaline zeolites (bases).
