Chemical filtration

In chemical filtration, water is passed through Activated Carbon or a natural mineral
called Zeolite. Activated Carbons are used primarily to make water clear and remove
potentially harmful chemical substances. It will remove color and odor producing
substances. Chemical filtration is most useful for removing particles that have got
dissolved in the water and substances that are too small to be removed through
mechanical filters. Usually, it helps to clear the yellow color that develops in aquarium
water over a period of time. Chemical filtration is also very good to remove medicine
lingering in the water after successfully curing a disease in your aquarium.
