Biological filters: Replace the carbon when the aquarium water turns cloudy, or at least once every two months. Chemical filters: Give the chemical filter a good cleaning out when it appears to be clogged, malfunctioning or working very slowly. More frequent cleanings may be needed if your fish is sick.
Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical absorption.Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.ach particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media.
