In an aquarium, water purity is essential to the health of aquatic life. However, impurities in the water, such as chlorine, dissolved organic matter, fish excrement and metal ions from aquarium equipment, not only affect the clarity and aesthetics of the water. More importantly, they can pose a threat to the health of fish and aquatic plants and even cause disease.
Therefore, ensuring the cleanliness and safety of aquarium water is a challenge that every aquarist must face. And activated carbon has become an effective tool to purify aquarium water thanks to its high adsorption capacity. In this article, we will discuss how activated carbon can help remove these impurities and keep the water clean.
Functions of Activated Carbon in Aquariums
Activated carbon is a porous carbonaceous material that can effectively adsorb impurities and contaminants in water. In an aquarium, activated carbon performs the following main functions:
- Elimination of harmful substancesActivated carbon can adsorb chlorine, heavy metals and other harmful chemicals in water, reducing their toxicity to fish and aquatic plants.
- Water purificationBy adsorbing organic substances and colorants, activated carbon helps to increase water clarity, making the aquarium look cleaner.
- Odor eliminationActivated carbon can remove odors from water, including those generated by fish waste and decaying plants.
- Improved biological healthBy reducing harmful substances in the water, activated carbon helps to reduce the risk of disease in fish, promoting healthy growth.
- Water quality stabilizationActivated carbon can adsorb certain substances that cause fluctuations in water quality, helping to keep it stable.
- Prolongation of the water change cycleDue to its ability to adsorb and remove multiple contaminants, activated carbon can reduce the need for frequent water changes, offering convenience to aquarium owners.
In summary, activated carbon is an indispensable assistant in aquariums, helping to maintain water cleanliness and biological health through its adsorption capacity.

Activated carbon is a highly porous material, whose unique structure allows it to play an important role in aquariums. The principles of operation of activated carbon in aquariums are described below:
Adsorption principle
The main working mechanism of activated carbon is adsorption. Its surface is covered with small pores and fissures, which provides a large surface area that can effectively adsorb pollutants and impurities in water. Activated carbon adsorbs through the following ways:
- Physical adsorptionThe molecules in the water form a film on the surface of the activated carbon, and as the water flows continuously, these molecules are adsorbed in the pores of the carbon. This adsorption is reversible, but under certain conditions it can effectively remove harmful substances in the water.
- Chemical adsorptionSome contaminants react with the chemical groups on the surface of the activated carbon, forming stable compounds. This method is effective for certain organic substances or specific metal ions.
Selective adsorption
The adsorption capacity of activated carbon varies for different substances. It can effectively remove the following components from water:
- AmmoniaAmmonia in water comes mainly from fish waste and uneaten food. Activated carbon can adsorb ammonia molecules, reducing its concentration and protecting fish health.
- Nitrites and nitratesThese substances are products of ammonia oxidation and are toxic to aquatic organisms in high concentrations. Activated carbon can help remove these harmful substances and maintain stable water quality.
- Organic contaminantsActivated carbon has a good adsorption capacity for organic substances in water, such as drug residues and plant decomposition products, reducing turbidity and odors in water.
Physical filtration
In addition to its adsorption function, activated carbon also plays a role in physical filtration. It can remove larger particles in the water, such as microorganisms, food debris and plant fragments, further improving water clarity.

The selection and use of activated carbon in the aquarium is crucial for water purification and maintenance. The exact choice should be determined by the type of aquarium, the design of the filtration system and ease of maintenance. Typically, the following are used granular activated carbon y pelletized activated carbon to purify the aquarium.
Granulated activated carbon
Granular activated carbon is selected from high quality coconut shells from Southeast Asia and undergoes strict activation treatment and fine processing to form a highly developed pore structure.
This structure gives the activated carbon an extremely strong adsorption capacity, allowing it to effectively remove a wide range of impurities and contaminants from the aquarium.
The microscopic pores of the granular activated carbon capture and adsorb organic substances, colors and odors from the water, which significantly improves water clarity and transparency, providing a cleaner and healthier living environment for aquarium organisms.

Columnar activated carbon is manufactured from high quality anthracite coal through a series of complex processes, and has excellent adsorption properties. Columnar activated carbon is tough, easy to regenerate and has a well-developed pore structure and a large specific surface area.
These properties enable it to effectively adsorb organic contaminants, residual chlorine, odors and certain heavy metals from the water. The use of column activated carbon can significantly improve aquarium water quality, providing a cleaner environment for fish and other aquatic organisms while reducing the health risks associated with water quality problems.

Frequently Asked Questions
Activated carbon is mainly used in aquariums to remove harmful substances, odors and pigments from the water, such as dissolved organic compounds (DOC), chloramines, chlorine, phenols, etc. Improves water quality by physical and chemical adsorption. Improves water quality through physical and chemical adsorption, making the water clearer and creating a healthier environment for aquatic organisms.
Activated carbon is no longer effective when it becomes saturated. This is usually indicated when the aquarium water starts to look yellowish or when water tests show elevated levels of harmful substances. It is generally recommended to replace the activated carbon every 6-8 weeks, but the exact time may vary depending on the conditions of use and the type of activated carbon.
Activated carbon is safe for fish and aquatic plants if used correctly. However, activated carbon can pose a risk to aquatic organisms if it reaches saturation and begins to release previously adsorbed hazardous substances. Therefore, it is very important to replace activated carbon on a regular basis.
Activated carbon is suitable for most aquariums, both freshwater and saltwater, but in some cases (e.g. medication) it may need to be temporarily discontinued. Always make adjustments on a case-by-case basis.
When using activated carbon, it should be ensured that it is not contaminated with powdery impurities that may affect water quality. In addition, the use of activated carbon in the treatment of fish diseases should be avoided as it may adsorb drugs and reduce the efficacy of the treatment. Finally, activated carbon should be replaced periodically to avoid adsorption saturation and possible release of contaminants.
