ABSTRACT:
A filter system for use with an aquarium includes a housing having a pre-filter chamber, a biological chamber, and a sump. A protein skimmer receives water flowing from the pre-filter chamber and returns the water to the pre-filter chamber, such that a portion of the water flows through the protein skimmer several times before being returned to the aquarium. The biological chamber has a drip drawer holder having drip drawers for holding filter media pads and dispersing water substantially evenly over biological media in the biological chamber.
