Abstract

A filtration system for a container, such as a fish pond, can include mechanical and biological filtering in a self-contained apparatus for attachment to a submersible centrifugal pump. The filtration system includes a base assembly, to which at least one mechanical filter can be attached, and which can accommodate biological media such as Bio-Balls. The mechanical filters can be a foam material, cylindrically shaped and detachable from a lid portion of the base for easy access without disturbing the biological media. A fountain sprayer mechanism, controlled by a two-way control valve, can optionally be used to provide a decorative effect. The filtration system and pump are easily separated when the pump requires maintenance without disturbing the natural ecosystem. By connecting two or more base assemblies in series, via a base coupling mechanism, the user can achieve increased filtering without the necessity to purchase and install additional pumps.
