A vortex mechanical power filter includes a filter unit 12 arranged within a vortex tank 10 such that water to be filtered, e.g. flowing from a from a fish pond via gravity supply line 22, impinges upon a side of the filter unit at an angle to cause rotation thereof. The filter unit can also include a polyurethane ring float 121 so that the filter unit is self-adjusting within the vortex tank. Within the filter unit, a vortex disrupter 20 can be provided to aid in rotation thereof. As the system operates, a water jet assembly 18 sprays a plurality of water jets onto the filter screen to gently clean waste therefrom so that filtered water can be continuously provided.
