Patent ID: 8763995

Claim:
An apparatus for creating surge in a marine aquarium comprising: (a) a movable surface configured to be in contact with a movable non-solid material, wherein, said movable surface is a rotatable surface with two stable positions; (b) a first material orifice configured to discharge a first material said first material being buoyant relative to said movable non-solid material; (c) a container configured to receive said first material, wherein said container is affixed to said movable surface in a force applying configuration, and said container is comprised of a first container part and a second container part, and said first container part and said second container part are configured so as to cause said movable surface to alternately move substantially from a first stable position to a second stable position when a substantial amount of said first material is in said second container part, and said first container part and said second container part are configured so as to cause contained said first material to be alternately released when said movable surface alternately substantially reaches said first stable position and said second stable position, and said first container part and said second container part are configured on said movable surface in such a manner that said first material orifice discharges said first material alternately into said second container part and said first container part when said movable surface is alternately in its said first stable position and said second stable positions; (d) a housing wherein, said housing is configured to support said movable surface, and said housing is configured to confine and direct said movable non-solid material, and whereby force applied to said movable surface by said first material in said container urges said movable surface to move said movable non-solid material that is substantially in contact with said movable surface through said at least one housing opening to create a surge in said movable non-solid material external to said housing (e) a third container part having a third outlet orifice configured to receive said first material leaving said first container part, said third outlet orifice of size sufficiently small so as to slow the rate of release of said first material into said movable non-solid material; (f) a fourth container part having a fourth outlet orifice configured to receive said first material leaving said second container part, said fourth outlet orifice of size sufficiently small so as to slow the rate of release of said first material into said movable non-solid material.
