I have moved into a house that has a garden pond that had a waterfall working. Unfortunately when the owners moved out they took all the equipment with them, the pump, filter and piping with them. I would like to get the waterfall working again. I have an Oase aquamax 6000 dry pump. I would like to know what filter and piping I should get and how to connect them all up so the waterfall flows again. The pond is 6' 11" long and 3' 10" width. The pond itself is 16" - 18" deep. The waterfall section is 24" in length and 18" width. Where the waterfall cascades down this is approx 2' 6".
