Is it good to filter water in the aquarium through activated carbon?

Fish is a very popular animal among people. There are many kinds of fish. Among them, those with delicious meat are suitable for eating, and those with unique shapes are suitable for viewing. When people raise ornamental fish at home, an aquarium is an indispensable equipment, which can provide better living conditions for fish. Some aquariums filter water through activated carbon. Is it good for aquariums to filter water through activated carbon?

It is a good idea to filter your aquarium water through activated carbon.

The adsorption principle of activated carbon is to form a layer of balanced surface concentration on the surface of its particles. The size of activated carbon particles also affects the adsorption capacity. Generally speaking, the smaller the activated carbon particles, the larger the filtration area. Therefore, powdered activated carbon has the largest total area and the best adsorption effect, but powdered activated carbon can easily flow into the water tank with water, which is difficult to control and is rarely used. Granular activated carbon is not easy to flow due to its granular shape, and impurities such as organic matter in the water are not easy to be blocked in the activated carbon filter layer. It has strong adsorption capacity and is easy to carry and replace. The adsorption capacity of activated carbon is proportional to the contact time with water. The longer the contact time, the better the quality of the filtered water.

Note: The filtered water should flow out of the filter layer slowly. New activated carbon should be washed clean before first use, otherwise black water will flow out. Before loading the activated carbon into the filter, a 2 to 3 cm thick sponge should be laid on the bottom and top to prevent large particles of impurities such as algae from penetrating into it. After 2 to 3 months of use, if the filtering effect decreases, new activated carbon should be replaced and the sponge layer should also be replaced regularly. The activated carbon filter pressure vessel is a pressure vessel filled with a coarse quartz sand cushion and high-quality activated carbon. A layer of balanced surface concentration is formed on the surface of the activated carbon particles, and then the organic impurities are adsorbed into the activated carbon particles. The adsorption effect is very high in the initial stage of use.

However, over time, the adsorption capacity of activated carbon will weaken to varying degrees, and the adsorption effect will also decrease accordingly. If the water in the aquarium is turbid and contains a high amount of organic matter, the activated carbon will quickly lose its filtering function. Therefore, activated carbon should be cleaned or replaced regularly. Adsorption principle Activated carbon is a very small carbon particle with a large surface area, and there are even smaller pores in the carbon particles - capillaries. This capillary has a strong adsorption capacity, and due to the large surface area of ​​the carbon particles, it can fully contact with the gas (impurities). When these gases (impurities) hit the capillary, they are adsorbed and have a purifying effect.
