ABSTRACT:
An aquarium cleaning arrangement characterized by the use of an open bottomed casing for selectively defining the boundary of a portion of the pebbles and/or gravel in an aquarium, and where water is pumped into the casing to achieve agitation therwithin and to dislodge and remove unwanted settled debris. A water recirculating arrangement is provided which includes a pump, a filter, and a water discharge system within the casing, the latter presenting stationary or fixed water jets extending into the pebbles and/or gravel and a rotatable member driven by water flow passing through angled outlet jets thereon. Provision is made for valving, forming part of the water recirculating arrangement, to achieve filtering of all water in the aquarium, i.e. including that which is outside of the casing.
