Abstract

A clamp 150 for attaching a power head (62 Fig. 25) to a wall of the aquarium tank (54) includes a suction cup 178 for attachment to the wall, a ring 168 which mates a tubular inlet portion 90 of the housing of the power head and an internally threaded tube 174 extending diametrically across the ring. Athreaded shaft 176 is disposed within the threaded tube 174 and has an end portion extending from the tube to contact the suction cup 178 and a rotatable knob 180 is fixed to the shaft for rotating the shaft, thereby to adjust the distance between the ring and the wall of the tank. <IMAGE>
