This pond is 4m x 1m x 1m and holds 4000 litres of water in and it needed something to top it off, for this Phil used the "Stowasis Niagara". Looks quite good if I may say so myself. The sun (Whenever that is these days) from around 0900 to 1300 reflects off Niagara and onto the centre stone circle, not planned, but a surprise bonus to the overall view on the garden.
