ABSTRACT:
A device for cleaning gravel and breaking up clusters of gravel in a fish pond comprises an integral body having a lower housing into which gravel is received and an upper housing which has an outlet for connection to a pump for drawing water and gravel into the integral body. The upper housing has a greater cross-sectional area than the lower housing so that the lower housing limits the size of gravel clusters entering the integral body from the pond bottom. A manifold encircles the lower housing of the integral body and has aligned perforations therein with the lower housing so that water introduced into the manifold radially and inwardly projects into the lower housing for breaking up the gravel clusters.
