Abstract
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.

Claim 5
Dependent Claim
128 words
A cleaning arrangement for an aquarium having side walls and a bottom wall covered by a layer of pebbles-gravel, comprising an open bottomed casing extending into a preselected area of the pebbles-gravel layer, and a water recirculating arrangement including conduit means communicating with said casing and a pump, other conduit means interconnecting said pump and a filter, and still other conduit means interconnecting said filter and terminating in a water discharge system disposed within said casing, said water discharge system including a water outlet member rotatable in a horizontal plane, said water outlet member including an angled jet receiving water to be discharged from said still other conduit means, and said pump being arranged to discharge said water through said angled jet to rotate said water outlet member.
