Man made pond – Rocks and stones give a courtyard pond a natural look while performing several useful functions. There are three types of natural rock. Sedimentary rocks such as sandstones and limestones are the softest. Limestone should not be used in fish ponds. Metamorphic rock like schist, slate, quartz and granite is more difficult and comes in interesting shapes, like lava, the molten magma crystallizes. The use of the rock that is native to your area creates harmony between the lagoon and the surrounding landscape.
Use rocks to shape the pond, support it and mix in the environment. Gradual levels shelves keep the sides collapsing and stacked granite stone field will carry out the lining of the pond to the shelves. River rock and gravel at the bottom of the pond are a surface for healthy bacteria that keeps the water balanced. Make sure the rocks are too large to be absorbed by a submersible pump.
The perimeter of the pond gets the superstar stones. Boulders with color, unusual shapes and texture attract attention so do not place them near any blemish. Instead, use them for waterfalls, ledges from the platform and the centerpiece of a rock garden on the side of the pond planted with the flowering of the ground cover and ferns. The flat rocks make the prey of a waterfall that leaves the water on the edge and towards the pond.
