In order to clear up this mess, it is best learn about the three primary roles of an aquarium filter system. These are biological, chemical andmechanical filtration.
Biological Filtration – Biological filtration use beneficial bacteria to propagate thewater and therefore invisible to the naked eye. Chemical filtration uses activated carbon or zeolite to remove the waste.
Mechanical Filtration – Mechanical filtration systems are probably the most common, basic and
This type of filtration system lets beneficial bacteria be present within the aquarium. In turn, these microorganisms convert the ammonia from the fish waste into nitrites, which in turn are converted by other bacteria into nitrates. While nitrates, in large concentrations, are still harmful to fish, they are easy to monitor and
