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 usually used in water filtration systems. In this illustration, the activated carbon is in the fourth level (counted from bottom). There are 2 predominant types of carbon filters used in the filtration industry: powdered block filters and granular activated filters.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.
