Canister Filter

As the name implies this one form of filter is essentially a closed tube, and has a channel or a channel with varying amounts ranging from 2 to 3 channel whose functions include the Inlet, Outlet, and Drain. But there are also products canister filter that uses 2 Inlet and 1 Outlet. Because the condition of water or filter media in a closed tube and allow the pressurized condition is very good for breeding bacteria decomposers. The downside of this type of filter is the event of power outages in a long time can lead to bacterial decomposition of dead and cause a bad odor and not infrequently even pollute existing water tank on diplay. Suggestions do wash filter media in water flowing through a rough dirt disappear (no need to use cleaning materials / soap) and then give the starter bacteria on filter media and then turn it back.
