This is the new Diamond Glass Pyramid Rig.  The size is perfect and the built-in diffused hole percolator functions extremely well and filters every hit.  The added halo rings acts as a splash guard and prevents water from traveling up to far from the bubble action.  The pyramid shape is just beautiful and creates a very sturdy solid design. It comes with a 14mm clear funnel bowl.
