Abstract:

A system is described for collecting, filtering and removing dirt, debris, detritus, active organic materials, chemicals and toxins from water in fish ponds and general aqua-culture applications. This system includes a filter tank with supporting base containing biological filtration media, a multi-port valve, a strainer, a diffuser head, and a quick drain assembly. The filter tank is fabricated using transparent material allowing for visual inspection of the mechanical and biological activities inside the filter tank. The strainer and diffuser head are slotted so as to capture debris, retain filter media, and maintain unrestricted water flow. The quick drain is a vertical tube covered by drainage slots. The top end of the tube is capped. The bottom end of the tube extends through the filter tank wall to the exterior where a drain valve is attached. The biological filtration media are hollow plastic cylindrical structures with ridges on the external walls and free-standing fins on the internal walls that provide a high surface area-to-volume ratio and thus can support a high volumetric density of naturally occurring heterotrophic bacteria.
