ABSTRACT:
The present invention is directed toward removing debris and impurities from the surface of aquarium gravel. The method comprises the utilization of a gravel casing, a pump and a filter, all interconnected. When the casing is held firmly against the floor the aquarium during operation, water enters into the casing by way of one or more apertures on the casing's wall. Gravel within the casing is thus churned with such velocity as to promote distinct patterns of water and gravel rotational motion which when sustained act upon the surface of the gravel particle.
