Abstract
A filtration device for tank water for aquarium fish having several partitions dividing the casing into several filtration chambers. A removable filtration cartridge is inserted into each filtration chamber. The cartridge has top and bottom panels with perforations formed in the panels to allow water to flow through the cartridge. The partitions are arranged in an alternating pattern. One partition has an opening near the bottom of the casing, and the partition extends to the top of the casing. The next partition does not have an opening near the bottom of the casing and the partition does not reach the top of the casing. This arrangement allows water to flow through the filtration device in a zigzag pattern. The removable cartridges allow individual filter mediums to be replaced without removing all the beneficial bacteria from the system.
