The uniring is a porous black hose which is coiled to form a ring and is connected to air pipe (from HI Blow). The minute holes in the black hose produce a lot a air bubble when the HI Blow is turned on.
Take note that the uniring is place at a small distance from the base of the pond. The bubbling effect cause a water current to move from the centre of the uniring towards the top of the pond. With the Air pump action, all the heavy fish waste that falls to the bottom of the pond will be dragged to the bottom drain (centre of uniring) via this small gap and being discharged. The discharge is assisted by air bubbling along the stand pipe.
