A skimmer filter assembly includes a hollow skimmer box including therein an accordion pleat weir-type water inlet, substantially vertically positioned filter mats and a submersible or external water pump positioned at the rear of the skimmer box. A filter mat holder and dirty sump retain the filter mats in a stable, slightly off vertical position and provide for removal of the dirty sump without repositioning the weir or water pump. The water pump is positioned in a portion of the skimmer box which is not vertically restricted, thus allowing multiple size water pumps to be utilized in their standard upright position without removing the mats to make room for large pumps and providing for servicing or removal of the pumps without disturbing the filter mats the filter mat holder, the dirty sump or the water inlet weir.

A skimmer filter assembly for removing surface debris from a garden pond comprising: a hollow box-like structure including a generally flat bottom wall having a periphery and a multifaceted sidewall extending upwardly from said periphery of said generally flat bottom wall completely therearound defining a front portion, opposing side portions and a back portion thereof, said front portion of said sidewall including a first aperture therethrough, movable weir means having a vertical and horizontal component mounted on an interior surface of said sidewall front portion across said first aperture for following a water surface of any pond on which the skimmer filter assembly is installed, said movable weir means including sealing means adjacent the bottom and sides thereof for preventing fluid flow through said first aperture except over the top of said weir means, said hollow box-like structure including a front filtering chamber adjacent said vertically movable weir means, said front filtering chamber including: portable filter pad means made of foraminous material for removing solid particles from any water passing therethrough, and means on said hollow box-like structure for maintaining said portable filter pad means in substantially vertical orientation therein, said portable filter pad means aiding in dividing said hollow box-like structure into said front filtering chamber, and a rear pumping chamber. 8. The skimmer filter assembly as defined in claim 7 wherein said means on said hollow box-like structure for maintaining said filter pads in substantially vertical orientation therein include, detent means extending inwardly from opposing inside surfaces of said multifaceted sidewall mediate said front portion and said back portion thereof and canted rearwardly adjacent a top thereof for providing a stable rest for any portable filter pads positioned thereon. 9. The skimmer filter assembly as defined in claim 8 wherein said detent means include an opposed pair of narrow elongate bridging walls dividing a wider front filtering chamber from a narrower rear pumping chamber, said opposed narrow elongate bridging walls also dividing said opposed side portions of said multifaceted sidewall and extending from said bottom wall to the top of said multifaceted sidewall. 10. The skimmer filter assembly as defined in claim 7 wherein said rear pumping chamber is unobstructed from said flat bottom wall to a top of said sidewall for allowing any pump means assembly positioned therein to be removable through a substantially open top thereof without the removal of additional structures. 11. A skimmer filter assembly for removing surface debris from a garden pond of the type having a plastic lining material defining the boundary thereof, said assembly comprising, a hollow box-like structure made of moldable plastic material including a generally flat bottom wall having a periphery and a multifaceted sidewall extending upwardly from said periphery of said generally flat bottom wall completely therearound defining a front portion, opposing side portions and a back portion thereof, said front portion of said sidewall including a first aperture therethrough, movable weir means having a vertical and a horizontal component mounted on an interior surface of said sidewall front portion across said first aperture for following a water surface of any pond on which the skimmer filter assembly is installed, said movable weir means including sealing means adjacent the bottom and sides thereof for preventing fluid flow through said first aperture except over the top of said weir means, said multifaceted sidewall includes a second aperture therethrough at a position below said first aperture, and said filter assembly further includes, bottom drain means positioned on top of any pond liner used in said garden pond, said bottom drain means including conduit means extending from said second aperture to a position adjacent the bottom of any pond on which said skimmer filter assembly is mounted for moving water from said bottom of said pond to said skimmer filter assembly, water inlet means at a distal end of said conduit means, and valve means adjacent said second aperture for controlling the flow of water from said conduit to said skimmer filter assembly, a pressure differential between said water inlet means and said second aperture, as mounted on a working ponds, providing automatic movement of water from adjacent said bottom of said pond to said skimmer filter and, said conduit means is positioned above any pond liner used in said pond and does not extend through said pond liner adjacent a bottom thereof. 12.
