ABSTRACT:
A biological filter for treating water in an aquatic system, composed of a porous water absorbing body of material adapted for rotation, and a member for supplying water to the body to be absorbed by a portion of the body so as to cause the body to rotate, wherein the member for supplying water to the body is composed of a receptacle located above the water absorbing body, the receptacle defining a water holding volume having a bottom, and the bottom being provided with at least one opening via which water flows out of the volume and onto the water absorbing body under the force of gravity.
