ABSTRACT:
An artificial pond reef is formed from sheet material into the shape of an inverted tub. It includes a peripheral base portion, upstanding sidewalls, and a roof. The base portion includes a horizontal flange extending out from the sidewalls. The sidewalls extend up to support the roof and include apertures for movement of fish and the like through the reef. The reef includes small holes for the growth of flora therethrough. The roof is configured to support and retain decorative enhancements (pebbles, sand, plants). The base, sidewalls, roof are surface-shaped and contoured to give the reef an appearance of natural rock formation. The reef is dark or black to promote bacteria growth upon it, and has a matte surface for bacteria to adhere to. The roof includes an opening to receive a removable receptacle for decorative enhancements.
