The role of activated carbon in the aquarium mainly includes purifying water quality, removing odor and pigment, and inhibiting algae growth.
● Purify water quality: Through its strong adsorption capacity, activated carbon can effectively remove harmful gases, small particles and organic compounds in the water, so as to improve water quality, and provide a healthier living environment for fish.
● Remove the odor and pigment: activated carbon can absorb the odor and pigment in the water, make the water quality become more clear and transparent, reduce the fishy smell of the fish tank and other bad smell.
● Inhibit algae growth: activated carbon also helps inhibit algae growth and keep the tank clean.
The following points should be noted when using activated carbon:
Cleaning: Before using, activated carbon should be cleaned to remove dust, but it is not recommended to use fresh tap water to rinse, because the pores of activated carbon may absorb chlorine and bleaching powder in tap water, which may have adverse effects on the subsequent water quality.
Replacement frequency: The adsorption capacity of activated carbon is limited, and it needs to be replaced regularly. It is generally recommended to replace it 1-2 times a month, and the specific frequency can be adjusted according to the size and water quality of the fish tank.
Drug use: When using the therapeutic drugs for fish diseases, the activated carbon should be temporarily removed to avoid the adsorption of the drugs and reduce the treatment effect. After treatment, activated carbon adsorption drug residue can be used, but it is recommended to remove after a few days of use.
Location: When the activated carbon is placed in the filter tank, it should follow a certain order: filter cotton (two layers) -biochemical cotton -activated carbon-glass ring-filter cotton (two layers). This ensures that activated carbon is fully functional, while preventing large debris.
Selection and use method: choose low phosphorus or no phosphorus coconut shell activated carbon is a good choice, because of its holes, strong adsorption ability, especially suitable for the use of fish tank. When used, the activated carbon should be placed in the filtration system to avoid being directly put into the fish tank. Simple daily cleaning is often not enough to completely remove clogged debris from the pores of activated carbon, so regular replacement is required.
